Spawning a rabbit sometimes spawn three rabbits.

When spawning a rabbit using a spawn egg or via /summon Rabbit, it occasionally spawns three rabbits instead of just one. I'm not sure if this is the way it was intended to work or if it's a bug, so I thought I'd report it.

Video demonstrating bug:

What I expected to happen was...:
When spawning a rabbit only one appears.

What actually happened was...:
Sometimes when spawning a rabbit, three appear instead.

Steps to Reproduce:
1. Start a new creative world in 14w27a/b
2. Get a rabbit spawn egg
3. Use spawn egg (it doesn't happen all the time, only occasionally, so it may take many tries)
