3 Days in a row now I have started finding a broken egg in one of the nesting boxes towards the front of it. This morning I had one hen just squawking up a storm like she was trying to tell on someone. I filled the water dishes in the run and she continued and finally went inside the coop. I decided to see what she was carrying on about and she had just got in a box and was pecking at an egg beneath her, like she was trying to move it out of her way. Like it didn't belong there. I reach in took the egg and she stopped and sat to lay.
Do or can a hen get possessive, not wanting anyone else to use her box? I have 8 nesting boxes and 11 hens. It is the same box I keep finding the broken eggs in.
