Good morning, if this has been discussed I apologise. Most posts seem to refer to multiple hens. I have 2 ISA brown hens who gave me their first eggs on 1July 2021. They have both been using the nest box quite happily until a couple of days ago when one has suddenly decided to lay on the fresh poo under the roost. She seems to lay quite early as by the time we get down there to let them out, the egg has become stuck to the poo and cracks when removed. I have tried removing the lid in case they were arguing over access but it didn’t help. Shavings changed yesterday and checked and fluffed daily. Clean hen house made no difference either as she lays on top of what they pooped the night before. When we lock them in at night they are both sitting on the roost coping happily. It’s driving me crazy. As it’s the end of winter I’m not keen to go down and brave the cold to stake it out and watch although they probably wouldn’t lay if I went down, they rush out to say hello. Help please it’s driving me crazy and wasting eggs. I’ve attached a photo of their humble abode showing the nest box in the corner sitting on a couple of bricks. They roost on the top rung which is a piece of 2”x4” timber.
Stay safe
