I have a weirdly picky JCP female. She was owned by a genetecist who had an unlimited supply of free lab mice. So for the first 6 years of her life she was fed mice. She won't take rats no matter what the trick. Got her on ASF but after 8 months she stopped taking them. BUT....she has never refused quail. I breed cortnunix quail and she loves them. Neat bird too, easy to breed and will go egg to egg in 7 weeks time.
