Wasps in feeder...

[ClarksMeadow]

I decided to give my weakest colony some 1:1 syrup and put on an eke with a round plastic rapid feeder half full. Came back a week later to find the feeder full of wasps. The only way they could have got in was through the hive entrance, which I had shortened when I put the feeder in. The colony is still weak, but there's plenty of activity and the super is full of capped honey. Where am I going wrong?

Why are you feeding them when they have a super full of honey?
