To bring this thread back to chickens, here are two in the nesting boxes at the same time. They like to share spaces. The one in the top left sometimes lays immediately below. The other two share the space the one in the lower right is occupying. If one is in the bottom and the other comes in, they cluck at each other until one moves, like waiting for the toilet. The other chicken lays across the coop. I've got enough nesting boxes for like 12 hens, but four of them wait in a line. Whatever.
