Day 3 since we got our 4 21 week old layers and they do not seem to want to come out of their coop! The last couple days I got worried they'd starve or dehydrate so put them into their run and closed the coop to force them to stay out and eat, which they did. As soon as I opened up the door again they went straight back in! Today I'm resolved to leave them to figure it out on their own. They won't starve themselves will they? How long will this go on for?
