We have 20 bobwhite quail that are now three weeks old. They have been moved to an outside pen that is plenty large for them right now, and are adjusting well (of course we still have a brooder lamp on them, and there is a roof over them. We turned over two five-gallon buckets and put hay in them, and they love them. My husband is raising these quail to hunt them, and plans on hatching more gradually over the years. In the meantime, he is building a larger pen for the quail. It's probably 20 ft long, 15 feet wide, and 12 feet tall, completely enclosed. It has a covered half. It is built with one side up against the wall of the barn. He wants to put a bunch of boxes in there. What are your thoughts on the nesting boxes, and the pen in general? Do they use nesting boxes? How many quail will do well in that size pen?
