I have a hen that's about 2 years old, she is molting and very scraggly, this morning i went out and she was walking around alittle, so i went to go get her and bring her inside so she could get some good food and warm up, as i went to get her she was standing in one place puffed up, so i brought her in and she doesn't mind being in a small cage inside, i went to check if she had gone potty and it's very watery and i opened the cage up so she could walk around alittle and she won't come out of the cage. she's obviously not feeling well so what can i do?
