I only ordered 3 chickens, but ended up getting 5. The dimensions of the interior of the coop is 30 inches long by 40 inches wide with separate space for 3 nesting boxes. My husband insisted on no larger than a 4 ft x 4 ft run, but I convinced him to also allow the under the coop ground space for the run, so that is another 30 inch by 40 inch space for them. 2 of our chickens are Bantam Silkies, while the other 3 are Golden Laced Wyandottes. My husband's friend has a coop the same size as what we built and at one point he had 7 chickens in it, so I am hoping ours is large enough. Worst case scenario, I figure we will just enlarge the run if they seem to be too cramped. I do not plan on free ranging at all because I am too concerned about the amount of predators in the area. The friend with the 7 chickens is down to only 2 now because he allowed them to free range and then watched as hawks swooped down and took out most of his birds, so I really don't think it's too safe in our area. Someone on another thread had said that the hardware cloth wouldn't be safe for the chickens to walk on while they are in the run during the day and that it could cause bumblefoot. Do you have any experience with that?
