Hello everyone! Sorry not the best pic I know. So this is my first winter with my flock. I live in Canada for reference. Overnight temps around -20c so far but will be getting down to -30c or lower soon. My coop is insulated, kept dry and draft free. (Open most days when it’s nice out and the chickens enjoy going outside, they don’t seem to mind the snow at all) I have lots of ventilation with no frost on walls or windows. The problem is my Barred Rock rooster has sever frostbite or so it seems. My other rooster is fine and so are my hens. I’m not sure why he has it so bad (and it is now worse than the picture as it was taken a few days ago) Has anyone else had this problem?
