can rabbits eat red kale?

because my dad got it by accident instead of curly kale and i wasnt sure?

Not sure if it's true or not but I was at our local organic market stall and he only had red kale, I was going to buy some and I told him it was for the buns and he told me that they should have the red sort. I didn't want to risk it.

i dont think they can...but wanted to check
