Hi! I am looking to build or buy a good-sized chicken coop / chicken tractor for my Silkies. I have 4, but would like to get around 10.....For breeding purposes. My dad likes to build all of our own things, but I ask him and he says he'll do it later, but It doesn't happen. Soooo, I am looking to get some good ideas for a medium sized coop that I can snug up to my old coop. He doesn't want a tractor b/c he doesn't like poop and feathers everyone. Lol. Any ideas? Thanks a bunch!
