chicksooner, I agree with you. Leave them in for a couple of days. That's a good plan. Then let them out for an hour or two (or three), herd them back into the coop and give them treats when they go in. RIGHT when they go in, not when you close the doors. Then close them up after treats. Repeat, extending the time they're out every day. They'll figure it out and go in by themselves. Do it at
early dusk though. Don't wait until 15 minutes before dark in case you need the extra time for herding. Train them to go in before they would normally go to a roof or the trees to roost.
This method works, and is worth the time. It's inconvenient to you only for a little while, but once it's done, all you have to do is go out and close doors and you have peace of mind and a much safer flock.
By the way, Peeps taught me everything I know, so I give her 100% credit for any suggestions I may have for others. I'm a 200% believer (not all are - this is just my opinion) in cooping fowl at night to cut the chances of being taken by a predator by 2/3. They give me eggs, keets, chicks and lots of enjoyment, and I give them as much safety as I can in return. Keep food and water in the coops, too.
But I believe in herding sticks. It doesn't matter what they are: PVC pipe, 2 x 4's (I used old strips of thin shoe moulding from the basement). One for each hand that extends about 6 feet from your arms. Go slowly, and never touch the guineas with it - they'll freak every time they see it from then on. Took me about 10 minutes to get the hang of it.
So I go out every night at early dusk, herd any stragglers who are reluctant to go in the coop if there are any, close the doors and go have a glass of wine. That's MY treat for getting everybody to bed.
