Is there a lot of moisture with your cold temperature, or is it too cold for that?You're right. On a related tangent, I've seen some really interesting things with a friend's coop that have made me wonder if the ventilation should-do's are different up here. I don't doubt they are helpful guidelines when you frequently go between above and below freezing, it makes logical sense then, but I can't shake this little doubt in my head that's telling me to go experiment with some things. Being me, I can't just say "it's good enough" and continue on as is, so I am going to try a new thing every year... and probably fail spectacularly in the process. I'm going to be getting maybe 20 Leghorns next year, so they'll be part of my tests.
One thing that took me an extraordinarily long time to realize is that even the peeps on here that say they have cold weather rarely have it to the length and extent that I do. Things are different, and there's not very much solid data that can be applied.The more southwestern places have very cold dips, but from what I understand, it warms up a lot in between. I'd also like to know if there are any other factors that have an impact on how much frostbite happens. What I would be overjoyed to see is a study with everything from temperature to barometric pressure measured and night-by-night photos of the combs affected by the conditions.
