I have one hen, out of 6, that will not lay her egg in the nest box. When I first moved them into their coop, she would lay in the nestbox most of the time. I noticed that at night, she was flying up onto a ledge (way up), but to get down, she'd practically crash onto the coop floor (or walls), and she would lay her egg up on the ledge. Most of the time, it would fall off and crack. So, I closed off the ledge, and added a couple more roosts. Now, she uses the roosts, but she still plops her egg wherever she happened to roost that night. At least it doesn't always crack now. She CONSISTENTLY lays the first egg of the day. I'm not even sure when it happens. I show up in the coop 1 hr after the coop light comes on, and her egg is already out. I really wonder if she lays in her sleep. I added fake eggs to the nestboxes, thinking that because she was first, maybe she needed some help knowing where to lay. Well, I got the rest of the girls to lay in different nests, but not her. I really don't know if this is relevant, but she's an ISA Brown, and she always lays very large, and slightly misshapen (bulged) eggs. Anyway, I'm out of ideas. Anyone else ever have this problem?
