My brother set up "The Swinging Bachelor Pad" in our mother's old greenhouse. The boys roosted in the rafters and everytime Mom moved a flower pot, they were all over the bugs! The greenhouse was on the other side of the yard from the chicken run. Losers of the Personality Contest got chopped first. When they had only three roosters left, Brother moved the boys back with the girls (who were finally laying).
I currently have a "Swinging Backelor Pad" and a "Hen House" side-by-side. The two roosters spend a lot of time pacing back and forth while they call the girls. I let the boys in when I put the girls up. ("Ack! Here come the boys! Run inside to bed before they mate you!") The roosters are happy to sit on the hen house all night, but if I think it will rain I throw them inside also.
