Hello all, we have a hen who has been sick for the last 6 days, I'm hoping someone can help. The first symptom I noticed was her droopy tail and listlessness. Standing with feathers slightly fluffed up, neck pulled in towards her shoulders. Less active than usual. By the next day she had very watery diarrhea containing bits of undigested corn, no blood. Her comb also started getting floppy and remains so, it is also a little lighter in color near the tips than usual. She makes very few sounds and they're at very low volume. I checked her crop a few days ago and it was down to about 1" in diameter and soft, as of yesterday afternoon, even after she'd been eating it was nearly flat. She has been drinking plenty of water and she is eating (crumbles, corn, hulled sunflower seeds, she also has grit available) but she is eating less than usual. She is still walking around and picking but half heartedly. She's not been preening much either. On the second day we decided to try Tylan which we continued through yesterday with no apparent results. Doing some research on her symptoms the one match I was able to find was sour crop, however I can detect no odor on her breath, could sour crop still be the issue? A little more information : She is a red star hen, we received her a few months ago from a woman who'd lost the rest of her hens to predation, I'm not sure how old she is exactly but I have the impression from what the woman said at the time that she's in her first year. She became a part time house chicken about a month ago, spending a good part of the day indoors and going to the coop at night. She has been in the house day and night since she started showing symptoms. None of our other chickens appear to be sick. Having taken her off of Tylan I am going to begin giving probiotics, I've also been adding a little sav-a-chick to her water for the electrolytes. Any ideas on what else I can be doing for her? Thanks!
