I've retired onto 10 forested acres in the Pacific Northwest (Washington) and have been thinking about chickens and fresh eggs for 3 years. Now, I'm about to be given 3 laying hens and a coop all ready to go. I need to learn quickly to give them the best home possible. I'll be looking for suggestions about free-range - or fenced for safety. How to best "varmint-proof" their coop and enclosed area. And what problems might I be watching for as they adjust to their new home.
