Shearing sheep in snapshot 14w17a drops different colored wool from agent.

Put the summary of the bug you're having here

What I expected to happen was when I shear a sheep, it drops 2-3 wool of the same color.

What actually happened was when I sheared a sheep, it dropped 2-3 wool of a different color from the agent (i.e brown sheep dropped light blue wool, white dropped black)

Steps to Reproduce:
1. Use shears on a sheep to get wool
2. Pick up the different colored wool
