I'm looking for advice on how to switch my girls to laying in new nest boxes. When we first got chickens, my husband made up a couple nice nest boxes in the coop he set up. But, before they really started laying, we moved and ended up leaving the nest boxes etc. behind because the person who bought our old house said he thought he'd get some chickens. The house we moved to has a large dog kennel, with a large doghouse inside, and so not being able to make another proper coop (yet...), we put the girls in there and that's worked just fine. Only problem is that they - of course - decided that the far back corner of the doghouse would be a great place to lay their eggs, so we've had to use a small rake (or lately, since one of the girls went broody, I have to crawl in there to get them) to get the eggs. It turns out that the person who bought our old house decided not to get chickens, and so we were able to get our nest boxes back. They're now in the coop, but the girls want nothing to do with them (they've been in there three days). I've tried picking a couple up to try to put them in there and putting an egg in there for a bit, even showing it to the broody one, and nothing doing. How can we get them to make the switch? And a related question - how big should the openings be in the nest boxes? When I lifted a couple of the girls up to try to put them in, the openings seemed so small! I think my husband used a measurement he found here or in a book, and I know they like it enclosed, but I'm just wondering if maybe the openings are too small and that's a deterrant. Thanks!
