hello everyone. i have been getting buckets from the bakery that has had cake iceing in them. i have been washing them out real good but got to wondering if i could start feeding it to my bees. i have 10 hives. some of the buckets have quite a bit of iceing in them, the iceing comes in every color in the rainbow. i have not given any to them yet for fear it might harm them. would like ya'll ideas on feeding it to them. thank you. mike.
