I have 31 hens and 12 nest boxes they fuss over them mostly everyday. I have a Banty Cochin hen that will sometiems go from nestbox to nestbox kicking any hen out of them screaming and fussing all the time. My Big Light Brahama Rooster - RIP Turd Ball - would hear this and he would hop up into a nest box, call the hens and they would get behind him in the box and he would guard them so they could lay their eggs. He would do this until Tweety clamed down. here is a pic of TB guarding his hens. There are two hens behind TB.
