Roos for eggs Newbie question

[abobwhat]

Do Coturnix hens need a Roo around to lay eggs or is it just about setting the right environmental conditions?

The roos only need to be in the pen if your hatching eggs..

Got it. Thanx

I wasn't sure if they like stimulated some primal urge to lay or something haha
