Hi! I'm hoping someone can direct me where to start with my 1 year old austrolorp hen who is showing some worrisome symptoms. About a month ago, I noticed some feather loss in her breast. She was pretty plump, so I thought her breast was rubbing something and causing the feather loss. There was no sign of lice or picking. It was a roundsih circle about 4 inches in diameter. I also noticed at that time a similar circle closer to her vent underneath, but only 2 inches in diameter. I've been keeping an eye on her and she eats well, acts normal. But, I just returned from being away for a week, and I can clearly see that she's lost some weight. Also, the bald patch underneath near her vent seems reddish and a little swollen. I don't think she's egg bound b/c she does lay - maybe every other day. I did notice a funny line on her egg this morning but the shell was intact. Any ideas?
