So for those that don't know much about Bovines ie: Cows/Bulls and even Bison this is for you.
If you are not sure where baby cows come from, here is a Cows nest. As you can see the eggs in this particular nest are all white. Now white eggs generally mean that the cow being born will either be a beef cow or a dairy cow that will only produce white milk. But if the eggs are brown (Which is more rare) you will end up with a cow that is used solely for the production of chocolate milk.
The more you know.
