I have a 4 year old Australorp hen that has recently been acting very lethargic. She's been getting slower over the last few days, an recently all she wants to do is sleep. But she's eating and drinking too, and will actually trot over to me when I bring the food bowls to her. However, she has white poop that almost has the consistency of egg whites, and when I picked her up to examine her crop, I couldn't feel it at all. All I felt was her breast bone. Also, she's always had minor breathing problems, but recently she's seems to be more congested and sometimes has to open her mouth to breath. Anyone know what is wrong and I what I can do for her??
