Sound familiar to anyone? I'm new in this and I have a hen who has been hanging around the coop for a couple days...I thought maybe she was going broody but then I noticed she was out and the other hens were picking on her. This morning she's fluffed up and you can tell she's not feeling well. Eating and drinking and poop is normal. Eyes and nose are clear and comb looks good. I felt her and I don't feel anything other than she is under weight. I have separated her that's how I know she's eating and poop is ok. How can you tell the age of a chicken could it be she's an old lady because she was given to me and they had no idea how old she was just told me a couple of years. Any suggestions help will be appreciated for this sweet girl.
