I got my first flock this past July and the girls are doing GREAT! We have 6 cold-hearty girls. I have a fairly small coop which I think helps keep them warm. I've resisted any heating for the coop because everything I read says don't do it! I've also read that you should't just wrap the coop up because it stifles ventilation. I have some wind tarps around the run that keep the wind from directly blowing on the coop, but that's it. I try to add vaseline to their combs frequently but haven't done anything to their feet. So far, so good, but we are about to have a big temperature drop this week and was wondering if I should do anything differently. This weekend we are going from highs in the mid 30s to highs in the single digits. (We are in NY). Any thoughts?
