This is one of my girls who shows broody crankiness when she's laying. She puffs up and rachets out warning language when I put my hand near. She won't budge off the nest for a while after she's laid the egg. She's not officially broody, because she does leave the nestbox within an hour or two. But do some hens get temporary broodiness just from laying? My other girls don't mind at all if I clean the coop, etc. while they're in the nestbox.
