they are wild birds. They roam & sleep where ever they are at when the sun goes down.I’m confused when you say they don’t come home. What’s the point of a Johnny house then? I’m sure there some attrition during acclimation.
Chickens come home to roost. Quail aren't chickens.
The house is to give them the option of getting out of the rain. Not all of them will use the house. In fact, a very good chance, none of them will. They lay eggs wherever they are when they are roaming. Like ducks, they give you an Easter Egg hunt every day.
I fully support you learning by doing. Please share what you learn.
