We currently have a small co-op that is half of our shed. We are going to be building a new one and I have some questions. We currently have 14 Jersey Giants and a mystery chick. Right now they seem to have enough room but I've seen how big these birds can get so we will soon need much bigger. We're planning on eating the chickens but want to keep some of the hens so we can replace our stock. I'm also trying to hatch out 6 svarts and 6 cemanis along with a few araucanas. We're also adding ducks soon. My question is how big of a coop should we build, leaving some room for more birds to come. Also where can I get free coop building plans. Thanks.
