I’m in Canada, and have had ISA browns, Rhode Island Red/Sussex crosses, and have Marans, EEs, more Sussex’s and bantam Cochins in the brooder right now. BUT THEY HAVE ACCESS TO AN INSULATED COOP THAT IS HEATED IN WINTER. Will they have access to a heated coop or any kind of shelter? It gets that cold here too, and we have a heat lamp on in the coop.
