I have six 15 week old pullets who have been all crowding into 1 or 2 nesting boxes in the coop at night! There is a perch long enough for all of them but when I out them on it they freak & jump off. Today they were free ranging in the yard & I found an egg in a little tucked in spot under a tree. First I thought they were too young but second how do I get them to lay & roost in the right spot?
