My son hatched some Gambel quail last Spring. They are beautiful and doing great we have 4 males and 2 females. They call and talk to us. THey have never laid an egg? We also wanted to know if they need hay or lighting to stay warm. They are on our porch in an antique wardrobe that was converted to a bird cage. It is pretty big, but we just want to make sure we have their housing right for cold weather, we are in South Texas. WE also wanted to know why they have never laid an egg. Any help or suggestions is appreciated. He built the incubator for home school--and did quite well hatching Gambels, Bob Whites, ducks and even a Rio Grande turkey..
