Boy have I had trouble with these chicks. It will be a miracle if they make it to adulthood. Just last week they had cocci. Now when I went in there the only cockerel was upside down in the feed dish limp. He looked dead. I grabbed him and he felt dead. I yanked him out and one side of his head was puffed up. I think he was on his last breath. I got him just in time. It took him about half an hour to look normal again. Now I am in there evry half hour checking on them.
