Just curious about the reason for this change: My 7 week old flock (5 pullets, one roo) have been roosting in the same spot -- on 1 roost pole about 5 feet long -- all together in a tiny area at the backside of the coop, nearly piled up on one another. But suddenly--in the last week, my EE pullet is roosting all by herself at the opposite end, right next to the door. Curious about the reason for this change. Ideas? I might have thought the roo (though immature) would be the one to roost next to the door, but he's in the pile with the other girls.
