Mine have nesting areas on ground level in their sleeping quarters and they love them
Jill goes on the top floor of a 2 storey rabbit hutch 'cause she likes to be different
They don't get their adult plumage until they are about 5 months old, but you can usually tell before then by the quack
Really depends on the breed with laying, my Runners hatched early june last year started to lay in November where as the calls didn't start till early Feb
