I've never had large numbers of birds in the coop, but one time I had a sparrow, and I spent 10 minutes chasing it around until I finally got it out the main door. I was very pleased to have freed the little bird. It flew about 30 feet from the coop, and was about 5 feet off the ground when one of my barn cats jumped up and snagged it right out of the air. I guess it wasn't that birds day!
