You didn't say how old they are, or I missed it. You could sprinkle a little scratch in coop before bed to coax them in. They will soon associate whatever cup or dish your bringing scratch in, and follow you in. My 5 week olds I've had to coax in a little earlier to their brooder coop to avoid...
I agree with everything you stated....mostly. You don't NEED to coop train by locking them in for 5 days minimum. I started with 4 birds/1 coop, increased gradually and now sit at 30 birds, 4 separate coops and have never locked any of mine down to home them to their coop.
I can agree that it...
