I'm trying to gorge my bees on protein this year to increase my overwinter success. I have had protein patties that they have been consuming but as we still have flying days i wanted to make some feeders. I made the 4" tube hanging ones and put them out but zero interest. of course the pollen got wet and moldy. those big blue feeders are out of stock. should i just continue patties or is there some trick to get them to start foraging and taking up the pollen substitute?
