I killed a good many mallards earlier in the season. They were coming into a big puddle in a cut field on my buddy's land. Some where landing on the 3 and 1/2 acre pond nearby, but most were hitting the puddle. Haven't seen any ducks since things froze up. I've seen a lot of geese out there but none will commit to my decoys. Hoping my robo goose changes that. This pond also has a windmill aerator on it and I'm hoping birds start using the thirty foot circle of open water caused by it with everything else being iced up. Anybody else seen birds drawn to aeration holes like this? This windmill was just put in this year so it may take them time to find it.
