I need some help with ideas of chicken breeds to research. I live in Alaska; long, cold, dark winters. I would like a chicken that produces medium-large sized egg. Something that has small or no comb to avoid frostbite. Where I live winter is 8 months out of the year temperature between -20 and 25 degrees farenheight. I will have a heat lamp in insulated coop, I plan on having large outside area for them and want a breed hardy enough to go outside at least in spring, summer, fall -temps 40-60 degrees. Thank you in advance.
