We have 7 original hens who just started laying. We gradually introduced 9 more younger ones that were almost the same size. They have gotten over the picking/pecking on each other. Our problem now is when the newer ones go in the coop for the night they go into a couple of the nesting boxes and pile up to sleep. They don’t get up on the roost! They are staggered in height and there’s more than enough room for all of them. How do I make the get on the roosts & stop pooing in the nesting boxes?? Thanks!!
