I once got slammed in the head by a bird flying out of the hoop coop door. I get out of the way now. I wait til they're all out before sticking my head in to check on things or do anything around the door. I was worried they'd gotten hurt. I know I did.
With the hoops they come flying off the roost and into the yard. The EE's can go pretty far too.
This is one of the reasons I'm glad I put in a pop door. I had them flying cause my roosts face the door and they would fly out. Also keeps them from trying to run under my feet to get in and out sometimes. I open pop door then main door but anymore with snow they don't want to go any where lol. I have to snow blow them an area again tomorrow since we got like another 5-8 inches I think.
