Guide talk:Breeding Cattle/@comment-97.113.110.137-20100807061122

This makes no sense. Why do the cows change breeds? I understand why FarmVille does not want players to get free rare cows through nursery barns but why does so many rare calves turn into chocolate cows when chocolate calves turn into holstein cows. What makes less sense is why common calves turn into holstein cows. I will contact Zynga myself.
