I picked up 3 hens the other day, being kept as per "industry standard". They weren't all that healthy. I've had them free ranging during the day (3/4 acre), free to mingle with the rest of the flock, but they're roosting in a separate area at night. It's been 5 nights and 5 days and they're starting to follow the flock around more, establishing pecking order, and following me around. I checked them for mites, they look pretty darn clean. The feathers they do have (they'd been pecked heavily from cramped conditions) now have a nice sheen to them. Their poos aren't stinky and awful anymore. When should I officially sneak them into the main coop with everyone else?
