Those older girls have paid their dues and made it there as well. They have earned the top roost.I'm rather sorry I went with this design now. I still like it aesthetically but when 20+ birds are vying for a spot on the top it gets more than a little crazy!I want the man to change them so it's in a U with everyone @ the same height but I just know there would be an outcry from all my older girls who love the top bar!
