Well, you can't control predators. You can control your chickens but only to a point. There are many here that can give you good advice on how to try to protect your birds as they free range. But know that even if you keep them locked up in a fort knox coop and run there can, and probably will, be losses to predators. If you free range you always take into account that there will indeed be losses. I don't free range. If I had a couple hundred chickens I wouldn't miss a couple fox dinners and would consider free range. With only 4, or 8, or 12 chickens losing 2 would be half ,or a quarter, or a sixth of my flock.How do you control predators while they free range?
