We have 4 grown hens and in a few months will add another 12 to the family (chicks now) and I was wondering just how many nests we need. In the 4'X8' coop that will be expanded I have 8 nests. I built them into the coop and am redoing them so they will set to the outside of the coop with a hinged roof..eaiser to collect the eggs. We have noticed the hens we have now that lay, only use two nests to lay in. I guess that is their favorite place to lay so why do I need so many?
