+2 on them getting aggressive once paired up. Me being caught off guard by just how aggressive they get is what nuked some of my plans this year. I had one male with 4 hens, it's just kind of what I ended up with in my large aviary. The male chose his preferred mate this year and they would team up and attack the other females to the point I almost lost a couple. I had to isolate/separate the paired couple from the rest.You can certainly eat the eggs if you like. They're a little smaller than coturnix.
Fyi in case you haven't gotten to that point yet, mated valley quail become aggressive/territorial, especially towards their own sex, during the breeding season. Depending on numbers and space.
Something I'm going to test next year is if they're in their large aviary and everyone has a mate, if that behavior isn't at least more tolerable. Maybe 2v2 spats rather than outright 2v1 murder. No clue if that'll work the way I hope.
