I want to build 3 coops right next to each other. One for silkies One for my pure bred chickens I want to start breeding and one for laying hens I fancy. I want fit about 10 chickens a coop and make them a nice sized chicken yard so they wont be pooping all over where my kids play.. I *think* I want an off the ground coop but one not to deep to where I have to lean over or climb into to clean. I have LOTS of field mice around here. It needs to be cost efficient and probly something Im gonna have to do alot of myself. The weather here ranges from 103 on the hottest and 18 at the coldest (which is very rare) Any ideas?
