This is my first time raising Cornish Crosses. All of them have poopy butts which I gather is fairly normal. However, one has a nice maggot infestation on his butt. I washed it to clean it up and in doing so found that a lot of his butt has been chewed up by the maggots. I am guessing I am going to have to cull him? Anyone have any suggestion on how to fix this?
