This is only my second season with 3 colonies.
2 of my colonies look 'normal' (whatever that is), building up well with no drones or even drone cells yet. The third colony also seems to be building well but there are several drones already and many proper drone cells around the edge of the brood nest (tops of combs).

This seems very early for drones??
Is it a sign of problems??
The queen looks fine and the rest of the brood pattern seems reasonable.
