We are planning our flock for next year and are particularly interested in hens that lay well during the winter. The breed index lists many birds in the category of high egg production but we dont need zillions of eggs in the summer. I know there are things you can do with light to get them to lay more in winter, but we would like a bird who naturally lays well year round even in cold dreary weather. Some must be better than others. We are in Brisbane, California. Thoughts?
