Momma has been raising some light brahmas that were sent with guineas. They were hatched on May 27th. Everything has been coasting along fine. Today she noticed that one of the chicks was a bit droopy and picked it up to look it over. The chick was very light weight compared to his hatchmates. Momma culled him this afternoon and did a short necropsy. She found a bit if food in the crop but nothing else of note until she got to the liver. She said there were green spots on the liver and wondered if that could give a clue as to the cause of his trouble. She said she had not ruptured the bile sack. I am out of town and don't have access to my vet book. Anyone have any ideas as to what could have happened to this chick?
