perry, you won't regret using the bee pro patties, it will go a long ways to helping them out. i started buying the pre mixed stuff a few years ago, got tired of mixing up the stuff myself, it's a chore. i stuffed some pre made bee pro with a shim on in late fall, i was concerned about the weight in the hive.
it was consumed. i place another half of a patty in just before easter, to cold to feed here, they had half a patty left. another check, that half was gone, and not out the front door. the hive was very light. it was warm enough this past weekend to put syrup on, and this week temps for them to utilize the syrup, but left the remnants of the bee pro in, just in case.
i didn't add a pollen sub, i see lots coming in right now, but they may change (until i can take a closer look soon), for you it is a good choice to add.
