Help!! We have 1 approx. 2 yr old White Leghorn that we rescued from a neglect situation in June. She has been doing GREAT until today. She has always been very friendly and talkative. This morning she won't come out of her nesting box. She is very quiet, has really bad diarrhea and she is drinking a lot. I took her out of her nesting box and watched her walk. She does not appear egg blocked. Can someone please give me some advice. I am VERY worried about her.
