I'm new to beekeeping and have a hive that wintered well. The days are starting to go into the low 50's and the bees are looking for food. I made some Megabee patties. They are eating it but not very much. I threw a pile of cracked corn on the ground for the birds but the bees seem to like it. They are rolling around it like they do with flowers. I'm not sure if they are attracted to it for the bright yellow color or they want the corn dust as pollen. Today I saw corn at the entrance of the hive. They are bringing it to the hive. Is this strange or what?
