One of my hens laid her first egg today! But, she went into the coop and got up on the roost bar and laid it on the poop tray below. My question is, will she learn to use the nest boxes? They've been ready to go with shavings and fake eggs in them for a couple weeks. I'm worried that if she did it once, she might continue laying from the roost bar. Any insight into whether or not she might make a habit of this? The egg was small and she's a huge hen but still super excited!
