I'm looking at three types of turkey. I only want to get one breed next year. My choice is the Red Bourbon, Standard bronze (not the broad breasted as I want natural mating), and the Narragansett. Can anyone answer a few questions? How big can they get, are they good in winter climates (East coast so a couple weeks at -30 and a couple months at -15 to -20) are they friendly? Any other points of interest? Thanks all.
