Hi, I am trying to move my tabby bee slot, but would it reset x1000 if i remove it and add back?
You don't lose your Tabby Love if you remove and re-add your Tabby Bee. If you "move" (read: remove from one slot and add to a different one) Tabby Bee, her bond level will change to the new hive slot's bond level. The only thing that you can lose if you use a Royal Jelly on a bee is gifted status: if you have a gifted Tabby Bee, for the love of all that's holy, don't ever use a Royal Jelly on it.
No, the only way an event bee can become gifted is with a star treat. They don't have favorite treats, so feeding them a bunch of treats at once can't make them gifted, and because their royal jelly is infinitely reusable, it can't make them gifted either.
