We have this 2 year old RIR that just loves to switch lay boxes. We even have a section of the coop isolated for introducing new chickens that has a box for them to lay in, and she will jump through the door when we go in to check on them, go straight to the box and lay an egg in it. We have three set up on her side, and she will be in a different box almost everyday. It's really cute. It seems like she is obsessed with the boxes. Is this a territorial thing? Or just her being quirky?
