Sorry

, I missed that question, your thread is super busy

!! I wish I could help you but I'm in Greece

!! There must have been something wrong with your incubator or with the eggs. I made so many mistakes ( the plug went off for half a day, It was a super hot summer ect) and I got 7 chicks out of 11 eggs but the eggs were mine so they were in good condition and they were all fertile. Were your females sexualy mature when you put them together? I made that fatal mistake. It's not enough to be 6 week old, they must start laying to be sure they are mature otherwise they won't accept him and he will probably harm them trying to mate. It's shocking how wild they can get. We must never forget they are wild animals. Even when you do everything right something will go south. I see you are very committed so consider changing to Japanese quails that are easier to find and search for a farmer near you that keeps them for egg/ meat production. I've read that button quails are more wild then Japanese. Your bird sounds happy so keep him as a pet.
The first 3 females I bought turned out to be 2 males, so make sure they are at least 4 weeks old and they have a lot of chest spots. Again, sorry I'm so far away that I can't help you.
I've seen a thread here asking "which State are you from". Maybe someone is from Colorado? I don't know how old you are, so ask your parents to contact. Keep safe and busy
