I was wondering if I needed to add light to the layer coop this winter to keep my young girls laying. I have BO as well.
My Cochins laid all last winter just fine without any additional light but I also have only a 3 sided coop for them. The south side is left open with only wire so they got morning til dark light in there and were allowed to free range.
I am hoping a lot of my new pullets of the many different breeds will do well for most of the winter.
I have heard that light plays the most important part of winter laying but those Cochins didn't seem to have a problem. Goodness knows they certainly don't get cold!
