I agree. I wouldn't open the next boxes up before 16 weeks. Sometimes as juveniles they will try to sleep in the nest boxes and when the sleep in them they usually poop in them and when they start laying you can get poopy eggs. My birds were sleeping in the nest boxes. I put milk crates in the nest boxes. It's no fun when they get used to sleeping in the nest boxes and then you reach in and get poopy eggs. This happened to me in the beginning. I thought it was cute. I finally got tired of cleaning the poopy eggs and the poop out of the nest boxes...
