One thing I would share is don't mix different species of quail chicks together. I had a brooder of button, different types of coturnix and bobwhite. Which was already a bad idea because the other ones were bigger but I didn't think the small buttons could get trampled. That wasn't how the poor baby button died- it was pecked to death and it was very gruesome. I could go into details but it might not be allowed on this forum. That was over 10 years ago and I still feel bad about it and traumatized about what I saw. Needless to say I separated the other button chicks after that.
