Too many pink sheep!!!

Put the summary of the bug you're having here

I Started up a new world to try out my uhc skills, on the second day i did more exploring and found some sheep, however the only thing that puzzled me was the huge amount of PINK sheep that i encountered! error in the code maybe? all together i found 6 pink sheep in a fairly close proximity, which i think is pretty damn unlikely!! (upon further exploration, i found at least 6 more, with at least one in every herd of sheep! this seems way to common to be luck!)

1.The seed is -6291231079333430901 didnt change any settings other than allow cheats to change the natural regeneration gamerule
