New Swarm?

Today I checked my swarm boxes and 2 of the 3 boxes had bees in them. I am still not convinced there is a swarm in them just yet though, maybe they are just interested in the pheremone. I'll keep watching in hopes to see a bee actually take some pollen into the hive. Then I will be confident there is a swarm /queen in there. I am loving these beautiful days we are having. Tomorrow after work, I am going to try to do some catfishing with my bud.
