My 9 month old buff brahma never left the roost this morning. She stayed in the coop while the rest of the flock went out to free range. She has slept all day and seems very lethargic. I checked her over and I see no sign of injury. I checked for egg bound and mites .. Her eyes and nose are clear too. Her crop is empty and soft .. She won't eat or drink even when I tried to temp her with her favorite snacks. I have her seperated in a hospital coop with fresh food and water and heat .. My outdoor cats who share the barn with my chickens had worms recently but the vet said it was doubtful that the chickens contracted it Any other ideas???
