More Realistic Wild Animals

Minecraft is made as realistic as possible, and I think this following suggestion will help with that. I know it will be hard to change this, because it’s been in the game for forever, but it’s not very realistic. Sheep, cows, pigs, and chickens all roam around in Minecraft as wild animals, but they’re farm animals not wild animals! I think that a wild variant of these would suit better such as a Thinhorn or Bighorn sheep for the sheep (these look similar to the new goat mob so maybe the wild variant of the sheep is the goat), wild boar for the pigs (the wild boar would have to be smaller than hoglin and definitely not pink, a dark brown or black is realistic) the Bison for the cows, and perhaps ducks for chickens that can fly. I’m not saying get rid of the normal farm animals though, they should spawn in villages and around them in the surrounding area since they are domestic animals.
