Another set of nest boxes probably isn't going to make a difference - they are creatures of habit and once they have found a place to lay, they will continue to lay there. The only way to retrain them to laying in the coop is to lock them in there for a week or two.We are making another set of nest boxes today. I have found a nice little active nest in my tree row along the road the other day. It had 7 eggs in it... I am hoping once I get more nest boxes in the coop, the girls who have been laying in the tree row will get back in the coop - any suggestions on this? I have a set of 3 nest boxes in the coop right now, putting another set of 3 today - I have 12 hens that are currently laying right now. (9 new little pullets aren't laying yet)
