Perching in barn not coop

[vocjuved1]

I free range my chickens but have a coop to lock them up at night for safety. I have half of the flock that insist on roosting in the barn. This is a real problem due to a predator that has decimated the flock. I rented a trap but had no success. I've had to move them off the barn supports they have made into perches with a broomstick. I then carry them to the coop. It's really difficult to lift them down and try to catch them, but necessary.4

I've thought of using a nail gun to put nails in the boards, but it's a lot of work, and there are a lot of boards.

BTW, the coop is hot and the barn is a bit cooler with our hot weather.

Any ideas?

Thank you!

Can the coop's ventilation be improved or a shade cloth added over top to help cool it down?

Can the barn be closed up at sunset, or does it not have doors?

They like the highest place, and I am betting the barn is that.

Can you hang some netting so they cannot get to the rafters?

If the coop is too hot, it probably needs more ventilation.
