Im not expert by any means but a North Carolina Wildlife officer came by just to check out my quail to see how they were doing and he even suggested that I might shouldnt have used the same pen I used to keep chickens in because of a particular mite that a chicken carrys that kill quail. He said he had that problem and lost most of his quail. I can honestly say that I have not had a single issue with them but I dont keep my in the same pen with chickens. I dont have chickens any more.
