true or false?

I have heard from somewhere that is true

Bob's burgers says that's true.

According to Encyclopedia Britannica, cows aren't very good at traveling down stairs and won't freely do so on their own, but they can navigate down stairs when forced to.

Yup..
They'll go down a ramp though.
But it needs to have raised rails across it so they wont slip..

I think it might be true. They can be pretty finicky about where they step.

I'm going to say false - cows can go up and down stairs.

.............false?

false, cows can fly

Why is that?
