Let us know, and good luck. Hi Leveret, it's Colleen again. I did some reading in my chicken health books last night, trying to find somethings that matched your hen's symptoms. There are a lot of things, so it can be confusing, but there are a few very common things that can cause paleness and droopiness. Worms, for one - round worms.
Piperazine takes care of that.
I worm my chickens about two times a year, because they run the property, and some are very bothered by them, others seem more immune to a bad infestation. Lice and other external parasites can also be the culprit. Adam's flea mist works well. There are some common diseases which cause paleness, but they have a long incubation period, and usually other symptoms - shriveled combs, discoloration, etc. Again, hope this helps.
