I keep a couple of hundred Japanese quail for eggs and meat.
Mine are mostly kept indoors in 3 tiered rabbit hutch type systems with my breeding birds kept in indoor rabbit cages.
Not bending down to pick up eggs is a huge bonus!
They have no concept of nestboxs, they will just lay their eggs wherever they are at the time and carry on.
I have a laying flock hatched last October which started laying in December which are still laying at 95% (95 eggs per day from 100 birds) although they are getting extra lighting, they won't lay anywhere near as many eggs on natural daylight outside spring and summer.
