message: In the article, it is suggested that a nice egg is a zygote, thus a cell. Is an egg (like a chicken egg) just a cell, or is it a container that contains one cell and other material to sustain the development of the zygote? The difference between a fertilized egg and an unfertilized ovum (which is also refered to as an egg, and, btw, most chicken eggs I eat are unfertilized) is not clearly made. The egg yolk and egg white articles suggest that they are the nucleus and the cyotplasm of the cell, up until fertilization, should this be mentioned in this article? Is there a universal structure or composition of eggs, both fertilized and unfertilized? I can't find a diagram of what a (e.g.) chicken egg is made of, and what structures it contains, should such a diagram be added? Anthony Liekens 22:12, 16 October 2005 (UTC)
replies: text: The german chicken egg article has such a diagram, there is no such article in the Englsih wikipedia. I think such a composition/structure has its place on wikipedia, either here or in egg (food), which I don't think to be a good place for that. What are your opinions on this?

thread_title:  What is the composition of an egg? 

message: OK, well I've cleaned up the page layout of images a little in order to avoid the use of galleries. In the process I removed a couple of the fish images that were less clearly showing eggs themselves. Although we have already got rather more images than text, as Anthony Liekens says above, it would be a good idea to add :Image:Ei1.jpg shown right - assuming someone can translate the labelled features.
Of more concern, I started to write the section on fish eggs and fishy reproductive strategies — now, as Sam Cooke might have said, I "don't know much about oology, don't know much ichthyology", so it would be a good idea for someone to check over this section and improve it. In addition there are some interesting things that could be said about parental care of eggs, particularly by cichlids and seahorses. -- Solipsist 09:33, 4 February 2006 (UTC)
thread_title: Images and fishy section

message: I don't have time to do anything with it at the moment, but the whole section on egg coloring needs to be gone over.  The overall impression one gets when reading it is that several different authors with widely differing opinions tried to sound like experts on the subject.  The section disagrees with itself!

message: I've removed the following
:In reality, the speckles of eggs provide extremely poor camouflague, summed up affectionately by ornithologist Andrew Gosler of the University of Oxford who claimed that "a blind weasel could find them." (see References §)
As it stands, it does not make sense - Gosler himself talks of the strong evolutionary pressure for ground-nesting non-passerines to lay coloured and speckled eggs as camouflage, and anyone who has seen the eggs of species like Ringed Plover will have little doubt of the effectiveness of cryptic egg colouration on the bare areas they use for nesting - white eggs would be instantly obvious to any predator in that situation, whereas the cryptic eggs are difficult to see even at close range.
I don't doubt that the quotation is accurate, but there must be something missing from the context, which needs clarification.
:OK. it refers only to Great Tits, which are hole-nesters and don't need cryptic eggs. jimfbleak 12:51, 4 July 2006 (UTC)

replies: text: I'm not quite sure what it was about the fomatting you didn't like, but I've merged the three very short sections into one, adjusted image layout, and removed an image that didn't make sense without a legend (the image with the caption "a good image to include" on this talk page).  I realise including the article title in the heading names is contrary to WP:MOSHEAD but I think it works on this particular page.  So for now I'm removing the wikify tag. Adrian J.

replies: text: Monotreme eggs are basically similar to reptilian eggs of the same size in internal structure. Also like most reptile eggs, they are semi-soft and easily dry out. Sex determination is genetic rather than temperature dependent. The young is very underdeveloped at hatching, similar to the young of marsupials. Petter Bøckman (talk) 07:56, 31 August 2011 (UTC)

message: I presume that before it ends up at 1.5 kg an ostrich egg starts off very much smaller inside the mama ostrich. How does it grow and develop? How does it get the necessary nutrients? And does the shell grow along with the egg, or does it form around the rest of the egg as the final stage of development?

message: I'm a little troubled that this article exists side by side with Ovum.   Any thoughts on a merge?   Note that human egg redirects to ovum, while egg (bird) redirects here.  This is not a good situation. arkuat (talk) 06:27, 3 June 2008 (UTC)

text: Support, but following the merge the topic would benefit from splitting to form linked pages for "human ovum", "bird egg" to cover ornithology, and perhaps others, which might take a lot of work. Snowman (talk) 11:27, 9 June 2008 (UTC)

text: Oppose: This article covers a complete multicellular structure containing a developing embryo; the ovum article covers unfertilized female megagametes.  These are entirely different structures. Although the former does result from fertilization of the latter, the result of that fertilization is the presence of a new organism which was not previously present. --EncycloPetey (talk) 21:16, 27 June 2008 (UTC)
thread_title:  Merge with ovum article? 

message: I got here from Hydrogen Sulfide as that article links here via the term "rotten eggs". However this article says nothing about what causes eggs to rot, or what causes the characteristic "rotten egg" smell. If someone knowledgeable could expand the article to cover this it would be most useful Manning (talk) 10:09, 1 June 2009 (UTC)
replies: text: That article currently implies that the smell is caused by anaerobic bacteria that invade the (otherwise sterile) egg and liberate the sulfur from the amino acids. Probably that article (or a more specific article on the kinds of bacteria) is the best place for section giving a detailed exposition of the topic. Nonetheless, it might be worth very briefly mentioning here somewhere here the degree of sterility (or absence of immune system) of eggs, in a way that directs the reader back to hydrogen sulfide if they want details about rotten eggs.

thread_title: Days til hatched?

message: The sentence reads:
:The term "egg" is used differently outside the animal kingdom, for an egg cell (sometimes called an ovum).
Animal kingdom redirects to Animal, and humans being animals as well, this sentence seems unclear.  Also, it appears that in some languages the term egg is often used for ovum, and in others ovum is almost exclusively used for mammals (e.g. in French).  If the intent of this sentence is to explain that in biology egg may also be used for ovum and vice-versa, or that mammal eggs may also be referred to as ova, it should probably be reformulated.  The current sentence appears to promote the unscientific idea that humans are not animals (perhaps involuntarily).  76.10.128.192 (talk) 03:19, 3 April 2013 (UTC)

message: Egg structure related to nesting behaviour. 
"We know that most dinosaurs, including the small relatives of birds, such as troodontids and oviraptosaurs, buried their eggs in the ground in nest mounds. ‘Troodon has elongated eggs that are sort of more vertical in the ground, and it seems like only the upper portion of the eggs are exposed.  So their eggs are also kind of buried’, Varricchio says.  This is more a reptilian trait.  
"One difference betweeen the brooding behaviour of modern birds and reptiles is that birds rotate their eggs to balance out heat transfer.  Crocodiles and turtles, however, go through a phase of development where if the nest is disturbed and the eggs are rotated, then the embryos die because they naturally adhere to one side of the egg, and turning them over means development doesn’t proceed properly.  
"‘Birds on the other hand have little cords of protein called chalazae that allow the embryo to rotate without affecting it inside the egg, so perhaps the buried condition of dinosaur eggs was a representative of a lack of this’, Varriccchio says.  ‘Dinosaurs may have been prohibited from nesting in open nests until they had that key feature.  So maybe they didn’t have what we think of as a typical bird nest up in the tree – eggs just kind of lying in a cup, or a little saucer of sticks and stuff like that.  Maybe they actually had to ensure that they didn’t rotate by implanting them in the ground.’
"Working alongside Frankie Jackson, also of Montana State University, and Darla Zeletinsky of the University of Calgary in Canada, Varricchio has shown that Troodon laid its eggs vertically in mud, half-buried them, and then most likely incubated the exposed parts by sitting on top of them and perhaps fanning feathers over them. …"
