I have 25 linear feet of roosts at various heights around my coop.
My dozen chickens stubbornly sleep on the floor of the coop.
My chickens sleep on the roost when they're in the hen house, but if I let them out, they stubbornly sleep on their old coop, which they didn't even like to begin with.
I feel your pain. lol
. I have twelve and I've gotten three eggs this week. Of course there has been the combining of two flocks together so I imagine they are stressed.
