Okay, so I'm out cleaning coops. I changed the hay in all the boxes except one. My buff orp was in it at the time with my Jersey Giant waiting below. About 30 minutes later I went back out to collect the egg and change it. This time My JG was in, I had a light Brahma waiting below, and my other buff orp was standing just outside the coop! It looked just like they were all waiting in line. I gave up, went inside, and later collected 4 eggs! There are about 18 different boxes in 3 coops, but they have to all lay in the same one!
