I had two pair of Valleys and one hen was killed by a cat. I tried two hatches and only got one chick, hoping it was female but no luck. kevin is now a spoiled pet and Little John is still calling for a mate. Any one out there have some females? Little John is two, and Kevin is 7 months. Can I keep all of them together this winter in one pen for warmth? It worked last year. This is Kevin with my daughter.
