I would say...don't try this EVEN if you Can watch them all day!
When I first started raisinf quail I mixed some BW of diffrent ages. Same breed even. They seemed ok. Made some wierd noised when I first put them together. I watched them for quite a while, until they settled down. I thought everything would be ok. Wentn out the next morning. Total masacre of the younger ones. Learned a hard lesson that time.
