Greetings, I have 3 beautiful chickens (of still unknown breed) still less than a year old. They are laying well but always in the same nesting box. I made 3 boxes all next to each other, but I sometimes see them queuing up to use the favorite one. They also used to have a secret nest in the garden, but i put a stop to that by leaving a big piece of dead coral (from the ocean) in that spot. It's not a big problem, but I'm curious as to why they do it, and if I can easily rectify it.
