Just found your blog! We live in Highlands Ranch and got 4 baby chicks from Murdochs last week. They are thriving in their brooder :) Do you have a heater in your outside chicken coop?
I'm so sorry for the delayed response.No we do not have a heater, just a heat lamp that is connected to a Christmas light remote. Our chickens are Rhode Island Reds so they are tolerant of the cold Colorado winters.
