Question for the beekeepers out there. I'm starting a hive at the end of March and one in early April. There isn't a heavy pollen or nectar flow in my area yet. We are planning supplemental feeding starting out but I'm also thinking of adding a pollen substitute to encourage brood rearing. The supplements/feeding will stop once things are in bloom here. I've found these three, does anyone have any experience with them?
