I just want to second the bit about vaseline on the comb. I have made a point of the coop being draft free but I learned the value of this practice from Ididarod information and hobby dog sledders in my area and use it on my kids. Yup, human ones, long before having chickens. My kids like to go out in all the windy snowy weather and their cheeks get wind burn or snow rash from eating the snow-- yes, I tell them it is wrong. So, when we go sledding or when the weather is down real low I put chapstick, lanolin, olive or almond oil, anything on there that I have handy to keep the skin protected. I usually use Burts Bees on them but chapstick or bag balm or vaseline works fine, too, and better than oils as a waxier substance lasts longer.
I have a can of bag balm. The only thing is I get to catch my roosters to do this... I have 10 pens for boys (don't have that many now) so that should be a lot of fun! How long does the bag balm last?
