The problem won't be if you can break ice. It's not that cold, you'll be able to with a hatchet or pickaxe. If the water hasn't been frozen for a week(which it hasn't) the ducks will see your open water. My advice is to take a couple doz full bodies and stand them on the edge of the ice by your hole and, pile all your floater on the water butt to beak, at the same edge.......money!
If you doubt this method, go to a frozen pond Wednesday and take a look at where all the birds are and how the congregate.
