I recently lost one of my quail to an unknown illness but prior to her death she was very skinny and we could see and feel her crop quite easily. Recently one of my other birds (who had no contact with the dead bird) has become more skinny and we can feel her crop more easily. She doesn’t seem ill other than that she’s behaving completely normally but I don’t see her eat very often. We have now separated her from the rest but it’s been about an hour and I still haven’t seen evidence of her eating at all. When should I try and contact the vets? My concern is nobody will be able to see her for a while because of Xmas anyway.
