how long does incubation take
Missing from the table (which will be corrected in the next edition) is the incubation period of Ebola virus, which is 2 to 21 days. I would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur.
Can different types of bird be incubated at the same time? This is more tricky. Different types of bird eggs have different temperature and humidity needs, and take different lengths of time to hatch. While chicken eggs take 21 days, for example, geese can take between 30 and 35 days and need a higher humidity level. Goslings are also more likely to hatch if the eggs are sprayed with water every day between days 6 and about 25, whereas chicken eggs need to be kept in humid conditions, but dry.
Unlike the egg of a bird, whose parentâs must keep it warm, soil temperature is the primary driving force in the development of an anole egg. This causes great variation in the length of incubation; eggs exposed to warmer temperatures develop more quickly than eggs exposed to cooler temperatures. Even when kept under laboratory conditions, anole eggs vary in their incubation time. In general, anole eggs hatch after 30 to 45 days.
