Derby, I'm glad you didn't overwinter your aggressive colony, it just continues bad genetics.
NB, Really, really reconsider topbar hives. Bees hate growing sideways, they always want to grow up and down. Where are you planning on storing honey flows? Bees resist sideways growth and if the honey is to the side or below the brood nest it will be as it doesn't exist. I kept bees for years and inspected 10,000's of colonies for the state of Iowa and would like to see you bee successful at beekeeping.
Clark, Your right, City's getting his colonies robbed out.
Efb was never the big issue for me because it was so easy to deal with, Terramycin powders/mixes, Afb on the other hand, infects the wood, comb, everything in the colony and is easily spread between colonies by drone exchanges. Early on, if I saw afb, confirmed by shrunken cappings and the brood stringiness test, I'd douse them in lighter fluid, bees and all, and burn them on the stand. Afb colonies never had a honey issue because they were too weak to gather excess.
City, Take your bee brush and sweep as many dead bees off your comb as possible. Dump the dead bees away from your colony site. Take your bee boxes into a beetight place to store till you packages arrive. Please don't count on swarms to repopulate your colonies, 2 reasons, uncontrolled genetics and there may not be any swarms for you to catch.
For beginners; Find a reliable, experienced mentor, seriously, you need some one to help you, join beekeeping clubs and attend the meetings, take beekeeping classes, watch beekeeping vids from reliable sources, the money and time you spend now will be repaid 100x over in honey and lack of frustration.
