I am wanting to get some Coturnix quail and trying to decide if it will be ok to keep them inside a building with cages or if it is better to keep them in outside cages. I have a small building with 12 cages built in it, they are 20"wide x 24" deep and 24" tall. I had bantams in them and used sand in them since they have wood bottoms. They have been santized and all, I just wondering if they could be used for Coturnix or should I build outside cages. It is heated in the winter with lights in it and I was hoping to keep egg production going during the winter months.Any thoughts from anyone that has kept them both ways?
