Hi - We are planning on getting back into chickens after a few years away from it. We live in Northeast PA and in the past, ran an extension cord out to the coop in the winter so we could give the chickens some heat. This time around, we plan on moving the coop, and where we want to move it to, it is going to be near impossible to get an extension cord to. I was researching cold hearty breeds and was thrilled to see Black Austrolorps listed - we have had this breed before and I thought they were the sweetest chickens ever - but my question is exactly how cold tolerant is 'cold tolerant'? Does it mean that they don't need a heat lamp if they have a well insulated coop? or just that they don't mind winter as much as others? I'm sorry if this is a silly question - I have tried google without much luck.
