So last summer I conned my husband into getting muscovy ducks because chickens are somewhat noisy. For a multitude of reasons, the ducks and I are just not a good fit. So what I have now is a 12x12x6' enclosed coop with hardware cloth on the bottom 2 feet and 2x4" welded wire mesh on the sides and top. The hardware cloth is buried a foot into the ground. I also don't have any predator activity in our yard, despite having double latching doors, etc. What I'm saying is, the enclosure is very secure. I see no reason to lock the birds up at night beyond them being in their pen. I need a feeding and watering station, roosts, and nesting boxes. It does get somewhat cold here during the winter, so I assume the chickens need some sort of enclosure area to stay warm when it's chilly outside. I don't want to go over the top with building a really insane coop, but I also want things to work well and be convenient. Of course I need to put a roof over at least part of the run, and tear the pond out, but what else?
