So I've completed my coop and my next step is finishing the inside. I've looked at a couple ideas for the roosts and wanted to get some opinions. The structure is 8x4,with 3 coops extending off the side. I was thinking of doing 2 roosts with a 2x4 running the 8ft length of the strucutre. They would be about 12 inches from the wall and about 18 and the other 27 off the ground. Is this good or does and anyone have any suggestions. Also this is a picture of the inside. Thank you!
