I don't think I wrote anything here about the new coop. I'm only able to be on intermittently.
They have a ton of space in the covered winterized runs, and only sleep in the coop, but I know what you mean. Can't say everyone's experience would be the same, and I haven't had really big personality issues yet that impinge too much on roosting time (hello, Diane), but whenever there was a squabble at roosting the smaller coop sometimes seemed to actually help, if one could get in the door. First it made it harder to chase anyone around in there. Bodies are physical blocks, plus one can't go around a wall easily, it would take a determined hen to displace someone not in their cross-hairs to get to someone else. Also bodies are visual blocks too. Everyone would end up yin/yang style, or beak-near-beak, depending, usually in a sargasso sea arrangement. They wouldn't move away & spread out when they had the space, and it's interesting that they still sleep this way so far in a space nearly twice as big. I haven't seen any patrolling like a hen can do, going along a roost or from the floor, mercilessly looking to pull somebody off

, though when it's still somewhat light and roosting is on everyone's mind, certain hens get chased out until darkness is upon them. That's Diane now, and all the Spuds when they were younger, or the Spuds now if they go in too soon. Hazel exerts complete control on roosting order and access.
