I have had my quail on deep litter for over a month now and really finding that they are happier and healthier. Finally got my system down. So every night I throw a new layer of straw on top of the litter and they love it. In late evening a few of them will dig out little round deep nests and lay there happy as can be. The nest locations are random and they are abandoned by the next day. They have started to prefer their own nests to the shoe box nests I had provided when they were on wire. I collect eggs right after dark, and notice that most of the time I will shoo a bird out of the nest and find lots of eggs. Like today I collected 9 eggs from one nest and 5 from another. And then there were 2 eggs randomly lying out. I was told that Coturnix quail are so domesticated they don't sit on eggs or make nests, but I see it with several of mine. And also in the wild do they lay eggs in one big communal nest like that? Or are my quail just seeing that it's a safe place to lay since they are vulnerable during that process? But then one is always sitting on the nest of eggs being broody, too.
