I have a 7 1/2 month old chicken who has had a bad limp in one leg the last few months. She recently started laying eggs and it appears she's also gone into a molt b/c her throat area is bare. A few nights ago I noticed that she is no longer roosting and is instead sleeping on the floor of the coop at night. I don't get to seem them much right now b/c of the lack of daylight and my schedule. This morning when I went to let them out I noticed all but my little Loretta (girl with the limp) came running out. Upon further inspection I saw that she was having a hard time standing up. So... I brought her in the house to feed her. She ate like a horse, which tells me she's not able to get around much to eat. I can tell she's lost weight b/c her breast bone is rather noticeable and she just feels so much lighter. My first instinct (after losing 2 others to sickness months back) was to have her euthanized but my boyfriend thinks we should keep her in the house and see if she gets better. I feel she's gotten worse and now it's cold outside... ugh. It was hard to lose the first ones but I don't want her to get to the point where she's in extreme pain or starves herself or falls trying to get down the chute in the run and hurts herself worse. Thoughts? Suggestions? Thank you.
