Drones on the ground

[Swiftgrade]

Hi Everyone

This morning I had a lot of activity at the entrance of a hive with some of the bees being much more aggressive than this colony usually is. When I got closer I could see a lot of drones on the ground outside the hive, many of whom had wings that look odd (to me at least). I attach a photo. The drones seemed to be unable to fly. Can anyone suggest what might be going on?

Thanks!

It occurs to me that this colony had a drone laying queen and I successfully requeened about 2 weeks ago. There were therefore a lot of drone cells in the brood pattern.
