Funny, I was watching my flock going into their coop for their sleeping positions and several of them seem to tussle over one or two spots which for reasons I cannot begin to understand seems to be a coveted spot. First image is the perches before they went to sleep. Second image, These two want to squeeze into spots that don't exist by wedging between two birds already in position. In the third image, they were able to squeeze in, but look how much space is still available to the right. the third image is IR showing their final sleeping position after dark. Funny how they squeeze into the space in back where the two boards intersect. Believe it or not there are 11 birds there. So they never even took advantage of the extra room available to maneuver, they just squeeze into spots that they seem to think were reserved for them. Reminds me of two people fighting over a pre-assigned seat on an airplane for which both passengers have tickets.
