Hello. I am new to this site and I was wondering if somebody could help me? I have 11 chickens and they ALL use just one box to lay their eggs. Although I have 10 empty boxes they all use one box only. I wanted to have a chicken hatch some eggs but due to the high volume of eggs, I don't know which eggs are new and which chicken to allow to sit on the eggs. I've tried closing their favorite box but then all of my chickens will only use the next and for some reason refuse to use other boxes. Any help or suggestions be greatly appreciated.
