I have 22 barred rocks. The pen is 36 x 48. On the back end the grass was tall this spring when I built the pen so I left it that way. I figured that would give them some place that had some shade and a good place for bugs to gather. My nesting box is a 10 hole metal box were the eggs can roll to the front. It's hanging on the wall in the house. Some of the birds use it. I thought the other day the egg count seemed low. My wife noticed last night that there is about 50+ eggs in the grass part of the pen. 2 large clutches of eggs and several singles all over. No one seams to be sitting on eggs. I have 1 rooster in with the hens. What is my problem? I do not want to get into the pen to collect the eggs.
