i have a (approx.) five week old silkie chick who isn't feathering out at all. he only has feathers on his wings and a few popping out on his tail. my other silkies of the same age have almost all of their feathers and aren't nearly as small as him so i'm getting a little concerned. i took a better look at him today, and noticed he's got a little bit of snot coming out of his nose, and i lifted his wings up and saw that his back is bare, as well as his rear end. it's strange because he is very active, alert, he eats and drinks totally fine, gets along with all the others, and his overall appearance doesn't give away any sign of illness... just the snotty nostrils, and the tiny-ness... i feel terrible about letting him get sick, but it really didn't seem that way. he just appeared to be runty to me. but anyway, i immediately separated him from the rest of my babies, (there are 19 others of various ages and breeds) and now he is in a small box with a heat lamp, medicated feed, and some scrambled egg (which is is gobbling up quite voraciously). i want to know if i should get him some medicine. i'm hoping he may just be a runt with a cold. they all live outside in a little heated hutch, and have been for weeks. it got rainy out here though, so i'm thinking perhaps he may have gotten wet and he had to way to heat himself up? ugh.. ): to summarize: -chick has a runny nose and is bare of feathers in some places, otherwise, totally fine; acting normal. -what is wrong with him? -what kind of medicine should i give him, if any? -and what other care can i give him?
