So if a shepherd is herding sheep, who's looking after the flock?

A shepflocker doesn't have a very good ring to it

It must be very confusing for the poor dears stuck in front of their screens, must quite tangle their brains

Geese come in flocks too, but they're also part of a gaggle.....

Or are flocks in the sky and gaggles on the ground? But sheep don't fly so why do they come in flocks?
Sorry
