One of my chickens went broody a couple of days ago and I got her some eggs to sit on. I've had a big problem with all four of my chickens rejecting nesting boxes and preferring to lay on the coop floor their whole life (they're a year and 3 months old now). I tried giving the broody a box with straw, and just straw on bare floor but she would just sit next to it and move her eggs. The floor has linoleum on it and is covered with shavings but now she's even kicking the shavings off and just keeping the eggs on bare floor. Is this safe for her and the eggs? I'm afraid they're gonna break with no cushioning.
