Hello! I'm new here, and recently bought four couturnix jumbo quail (one male and three females) from my neighbors. I've read up on how to care for them and have them set up in a coop. However, my neighbors said they've never laid, and also that they're related. The son of the neighbors is always carrying them around and playing with them, so I think that the stress is why they haven't laid. My question is if they are related and I wanted to breed, would I be able to? Thank you!
