I have a 8 week old buff orph that has been acting strange. I've been reading up on it but nothing quite fits in with her symptoms. She is 1 of 3 buffs that I got as a babe and has always been a runt. As of right now she is about half the size of her sisters. She is ok most of the time but whenever she eats mucus comes out of her beak and she struggles to get the food in, same goes for water. I know something has to be getting through because she poops like normal. She is fluffy but really skinny underneath and I can't really feel her crop. She's pretty mellow most of the time and sleeps a lot. She has no wheezing from what I can tell. Just today I noticed her beak and feet are slightly grey. Whenever I think she's getting better something else shows up. Please help, any thoughts? Is she contagious? Is there anything I can do for her?
