Hi! This week we purchased 4 pullets (hopefully). We have a small fenced in backyard which we will keep them. Our plan is to have them out in the yard most of the time we are home, and of course put them in the coop at night. We ordered the coop and put it together tonight and I see a couple of things I’m concerned about. 1. Too small...is it too small for four hens (ISA Brown, California White, Black Asian, and Barred Rock)? 2. The roosting bars are the same height as the egg laying box, I read it should be higher than the boxes so they don’t go in and sleep and poop in the boxes. If they mess in there I guess I will put removable chicken wire cut to size to block the boxes. Maybe 4 nails, one in each corner to hold the wire and do this each night and remove in the morning. 3. Ventilation...I don’t see any ventilation up high, all I see is some little spaces around the poop tray to allow a tiny bit of circulation in, I can’t imagine it would be much. We live in Kansas City, MO and although they may stay huddled together and stay warm in the winter, the summers are HOT and HUMID even at night. I’m afraid of them getting too hot and stuffy rather than too cold. Should I drill a couple 1/2” or 3/4” inch holes around the peak of the coop for ventilation? Thanks so much! I’m trying to read and absorb as much information as possible on this new venture, but it seems there is no better knowledge than experience...which I’m trying to get. Thanks again for any advise you can give me, I’ll take it!!
