Hi All! I just bought two beautiful black mottled d'uccles pullets without researching them first. (I just fell in love I found a site that says they are not hardy. I live in VA and need to know if I need to do something different in our hen house as far a heat is concerned for the winter. (I have no supplemental heat currently) I will eventually put the new girls in with my laying hens. I'd appreciate any suggestions.
