Hey, good work!
We also had our first swarms this year... I was late in opening the nest (2/3 LR) and the bees decided to go for it. Each of the 3 hives cast 2 swarms; with a lot of help from a local veteran beekeeper all but one were caught. We've had all sorts - the highest was on a neighbor's 25 ft apple tree and the lowest one was, well, on the ground in a raspberry patch.
The last swarm appeared just as it started to rain and settled on a small apple tree just only 15 ft from the hives when the raindrops hit it. My helpful veteran was not available at the time and the rain was increasing so I did it myself - shook them in a cardboard box and wrapped it in a sheet. The bees were at about 6 ft height and very subdued because of the rain - it's hard to imagine better conditions for a first-time catch.
Then it was time to worry whether the new queens in the old hives "took"... At the moment at least one of the old hives has definitely got laying workers so I put an open brood frame into it from another hive - according to M. Bush etc this is a better approach than shaking all the bees out at some distance and introducing the queen. We'll see. The other two seem to be on a good path though.
The swarm from the neighbor's tall apple tree, the one hardest to catch, was of course also the largest. It's going full steam ahead, the queen is laying like a handbook picture so we already moved 2 frames of covered brood from this one into the weaker new hives + the one of open brood metioned above.
Right now we're in a sensitive spot - spring forage is done; as much of there was of it after a late frost. The next big event are pumpkins in 3 weeks or so. Keeping fingers crossed for all the girls.
