Hello BYC, This is my first post here, but I'm hoping to get involved in this community. As a teenager in the suburbs I kept 5-6 chickens at a time for eggs. I'm an adult now and live in the city of Seattle, and my partner and I are gradually learning to garden and urban homestead on our 4,400 square foot city lot. We recently got four chicks--a RIR, plymouth rock, buff orpington, and araucana. We were planning on building a chicken tractor so we could move the coop around, but I wanted to see if a chicken tractor would be sufficient housing for four backyard chickens. Or would folks recommend a more permanent coop than a tractor? We have a fenced in back yard--about half our lot--and plan on letting the chickens out in the backyard during the day. As far as predators go, there are plenty of dogs, raccoons, and bald eagles in our neighborhood. I would appreciate any advice on urban chicken keeping so we can build the best kind of coop for our small yard. By the way, the mayor of Seattle recently upped the maximum number of birds from three to nine!
