I'm in the final stages of designing my coop and I have a dumb question, round or square roosts?! I bought some 3/4" round dowl for my roosts but looking around it seems like everyone is using 2x4's. My chicks are a few weeks old and love the bamboo roosts I built for them but should I use 2x4's in the coop? When I previously worked at a wild bird rescue the round roosts were sooooo much easier to clean so I thought that it would be a better option. Also, what do you line your nest boxes with? I bought some large plastic boxes to use for the nest boxes so they're easy to clean and I was considering using some AstroTurf to line them so I can easily hose it off every few days. Ideas? Thanks!
