I have a 2.5 year old Barnevelder hen that has started crowing! She is definitely a hen, and had been laying lovely dark speckled eggs for about two years. Recently I have not had any eggs from her, but I figured that she was not laying in the coop as they are free-range. Also, we have recently lost our rooster. She was his favourite. Is all of this related? Has anyone else experienced this? It's very strange!
