Hello! We are in the planning stages of a coop and run next to our garden plot. We have 4 acres next to the river, so lots of hawks and foxes. Planning more for a big run (120'x20') than free range due to predators. Our main purpose is for our toddler age grandkids, and quality entertainment...oh, and eggs. I'm most concerned with keeping our flock healthy by means of prevention. Diseases are my biggest concern. We'd like to start with 6 adult birds from a reputable source in the spring, then add a couple each year. I'd also like suggestions on breeds with priorities in this order - good with kids, cold tolerant, good layers, diversity in eggs, not broody. Looking forward to some great info!
