dnd 5e – Can I use conjure animal to drop cows on targets, dealing damage?

I’m asking because of the fact that the feys take the shape of the beast, a cow, but, since the feys are spirits would they do any damage if they fell on an enemy?

Can cows that I conjure using conjure animals fall onto targets thereby dealing damage?
