Yeay it's all grey but bowmen are still working hard, i know it because of the song :)

You are wrong storm crow, there is a specific sound when an arrow hurts the rabbit. Also look closer : Arrow shock deals 2 damages to minions without shield, not rabbits :)

I would also say that some rabbits are wandering wounded, which explain a one hit dead.

Also there are different colors of rabbits from white through blue ?
