I have a 17 week old pullet who is ill. We just returned from 12 days of vacation, and my pet sitter didn't notice anything wrong, so I'm not sure how long she has been sick. The biggest concern is that she has lost quite a bit of weight, she is significantly smaller than her hatch mates of the same age. She also doesn't want to stand up, but I am not sure if she is just really weak or if something is wrong with her legs. Her crop felt quite firm, so I massaged it a few times. I was able to get her to eat some shredded cheese, grapes, and some feed, appetite seems somewhat normal. She did poop after eating, poop was small but normal. She was wormed just before we left for vacation with safeguard, she hasn't started laying yet, and I don't feel anything in her pelvis. She is alert and awake, makes noises, and does get up and stretch. She does have a mild case of fowl pox, I checked her throat and it seems clear. She did not have this before we left. In addition to the weak legs and weight loss, she keeps clicking her beak, not something she normally did before. She had a wet sneeze also, but no smell around her face and breathing seems normal. She has been holding her wings out a little bit. I guess it could be cocci, although they were treated for cocci about four weeks ago (no signs, but two newly hatched chicks died suddenly, so I treated everyone in that pen.) I am a bit confused, and don't want to treat the wrong thing. With the weak legs, I was concerned for Mareks, really hoping it isn't this. Would an impacted/slow crop cause these symptoms? The not wanting to stand really worries me. Thanks for any input!
