So remember, the only dumb question is the one not asked! I'm not sure what the measurements are of your coop door, but chickens will squeeze thru things w/o squeaking to much I cut a hole in the general flock pen last year, to allow them access to more area. I've got several JG cockerels that now have to stoop and hunker a bit to get thru the hole but it doesn't hinder them at all. It's what they're used to and as they get a little wider, I'm sure they'll figure it out.
