Thanks Rusty,Mega Bee is my favorite sub whenever I don't use my own recipe. I've got patties on my hives right now--but I am WAY farther south than you are. Best bet is to check with local beeks on the timing. Once you start feeding pollen, don't stop until the bees are bringing in plenty on their own. They raise brood on patties and if the patties suddenly disappear without any pollen to replace it, that big new population can starve.
