We got 6 chickens and a duck (all supposed to be good layers) last week and only one of them has been laying, as far as we can tell. She's given us an egg per day (except Sunday), but, the others aren't seeming too into laying. Is there anything I can do to get these girls to start laying? I've tried adding pepper to the food. No luck there. There's a light in their coop that's on a daily timer. They get plenty of protein. What's a chicken mama to do?
