When I got home from work today, one of my girls was in a nest box with her head towards the back corner and around her vent area was blood, but not gushing or anything, just "there". She is lethargic and didn't mind when I picked her up and put her in an isolated cage. Usually she pecks and runs away from people, but now she is just laying there with her eyes closed and her vent is moving in and out. I tried to get her to drink a little water and she did, but not much. Will not eat anything at all. She is approximately two years old and I have had her since April of this year. Any ideas as to what caused this? As I said I was at work all day and DH noticed her listlessness, but assumed she would be ok. Help please!
