To block that one I simple put a milk crate in front of the entrance. Open up the coop in the morning and let everyone out. The hens that lay in the coop are normally finished by noon. After the egg rush go out and remove the milk crate so she can come out on her own. I give her time but if she has not came out in a few hours, take off the lid and carry her out. I stay outside while she does her thing, most times she is done in around 15 minutes and runs back to the eggs. Once back on the nest put the top back on and replace the milk crate.How does the hen get out to get food and water?
