My girl is about 6 months old and she is lethargic and not acting herself. She normally does not let you touch her and now she just lays there. She is still eating, drinking and using the bathroom. Her stool is loose, but not diarrhea. She is still walking, but having trouble keeping her balance. She weighs about the same as before. I checked her vent and it looks normal. This is the 3rd chicken that has been like this, but the others died. I do have her separated from all of the others. This started last night. Please, any help would be grateful. I have a call into the vet.
