I have 8 nesting boxes in our coop. Is that enough for 2 roosters and 14 hens? Am I supposed to be cleaning them out? They roost in them every night and poop like crazy. Do I need to get them some hay, straw or pine needles to build nests out of...So far they have laid no eggs...they are 4 1/2 months old. Sorry but I'm a real rookie!!!
