Sugar 5:3 boiled water, Apple Cider Vinegar and Camomile-Nettle-Yarrow tea
I feed the bees behind the follower board in inverted glass jars. This jar was emptied after only one day :) Time to refill ;) 4 out of 10 colonies din't want to take the sugar syrup which is a clear sign that they have enough honey. I knew that already but wanted to double check just in case. The other 6 colonies emptied the jars in just one day. I will feed until they stop taking in.
It is not easy being a Wasps inside a Honeybee hive :) At this time Wasps and other bees are trying to rob honey from bee colonies but my ladies seem to be very good at holding their ground ;) I did reduce the entrances to help them defend it better.
