I have had chickens for just over one year now. Recently, the ladies have begun to perch/roost on the bar outside of the nesting boxes...heads out of the box and tail end in the box. They are pooping into the entrance ways of all the nesting boxes! YUCK! This is a new behavior and I want to discourage it asap. The girls (36 of them), are located in a three stall barn. They have seven large perches in the coops, and I added one more in case they are feeling "crowded". There are six nesting boxes in each of the two main coops (stalls). I have removed the comfortable bar from outside of the nesting boxes to try and discourage them from pooping where they lay. Some of the girls are being stubborn and sitting on the thin edge of the boxes anyway. Advice is welcome.
