Hi! We live in Idaho on 2 1/2 acres. I would love to get 3-4 hens for eggs and for the kids. I'm wondering what the best coop would be to buy/build. I've looked around and they are so expensive. I really like the idea of turning a doghouse into a coop. Our winters tend to be pretty cold and I know we have predatory birds, fox, and rodents. Is it better to get a portable coop or a stationary one? How much should I plan on spending on a coop? Any and all help would be terrific! Thanks!
