Similar problem - I have 11 hens and one rooster, and I've been diligently moving them onto the roost every night for over a week now (they are 13 qwwka old). I have one long 2x4 roost with plenty of space for all, and a ladder on one end to help them up. Four of them, sometimes five, will roost on their own; two of them cram themselves into the corner and are basically almost on top of each other. The others all congregate across the coop on top of the nesting box unit, which is basically a big box with four nesting boxes built into it. This big unit is right against the wall under a window, so they all crowd up there in a pile, pressed up against the hardware cloth of the open window. They used to ALL cram onto this box until I began moving the to the roosts. I'm not sure what the attraction is - sleeping in a pile, the open window, or what. Ideas, anyone??? Then I began thinking that once the big gals were situated on the roost, maybe nobody else wants to climb the ladder and take the spots farther down the long roost, since they have to walk past the alpha females?
Do I just leave them alone and let them work it out? Add a second ladder farther down? Aaargh!
