I have one chicken who spends her time kicking straw out of the nesting boxes. She will spend most of her time in the box, outside of it, half in it, etc, and now I've noticed that she slowly (over a couple days) takes all the straw out of the boxes! Anyone else have a chicken that does this? I'm not sure what's up with her..if she is going broody, or if that's just her spot and her thing to do. THanks!
