Hey everyone! I hope someone can help me out here. I have an almost 3 year old leghorn who has some type of an issue. Sometime last week I noticed her hunched and ruffled outside by the door to her coop. It was a super cold blustery day, and there were one or two other chickens with her so I thought maybe it was just the cold. This weekend I noticed her out with all the other chickens, but they were foraging an she was just ruffled and pretty still. Later that day I noticed she had yellow poo on some feathers. So Tuesday we wormed everyone, hoping maybe it was just worms. This morning she was hiding under nest boxes, but came out when I went into the coop. She drank some water, and had a little food. I was thinking maybe she was feeling better. This evening everyone had put themselves up but she was outside still. She's never been the last one in, and at first thought maybe she was blind. But she moved towards the coop and seemed to navigate ok. I ended up just picking her up to feel her over and put her up on the roost. She felt extremely thin. She's always been small anyway, but she is obviously in some type of trouble. What are your thoughts and opinions? I was thinking of getting some antibiotics to see if that would help her out, but I hate not knowing what I'm treating for.
