I have chickens and turkeys together without issue. I let the turkeys free range during the day, and they roost with the chickens at nite. No issues at all. Hope this helps.
Oh the mystery of the pip!!! I have had em take as short as thirty minutes, but as long as a day. The problem is if the Chick dries out, or the membrane dries out, the chick will get stuck and be unable to pip/hatch.
I watch the Pipped egg very carefully and make sure the humidity stays above...
