I have 11 hens 5 which are laying. The rest will be laying any day. I have 5 nesting boxes and they all want to lay in 1. Now here comes my problem 3 of them lay at about the same time. 2 take a little time to lay. They are beating each other up over the box. Sometimes it gets bloody with the pecking. How can I encourge the others to use a different box. I have tried the golf ball trick, plastic eggs etc.... I am scared that when the others lay that they will also want to use the same box.
