no problem. i lived in the interior of alaska for 26 years. i have seen the tiniest chickadee hold on to a frozen branch with those toothpick feet in -60F real temperature. this temp will cause steel axheads to get so brittle they can break and cups of coffee float away in a puff of ice crystals when thrown in the air, yet those little toes remain flexible.
