I've read here and there that some people have kept male Coturnix together for long periods of time for various reasons. I have a group of about 20 birds aged 1 week and I want to let them develop before I decide which male(s) to keep. As they get older and the sex becomes clear I plan to separate out the females and have just males for a few weeks. How risky is this? Will they peck each other or otherwise hurt each other if I have, say, 7 or 8 males together temporarily? Just looking for others' experiences.
