Baby Chicken!

When i was sorting out my inventory, I noticed one Egg. I decided to get rid of it as it was just using up inventory space. Instead of destroying it I threw it at my sister (she was playing on my SP map at the time) and to my amazement it turned into a little chicken! This only has a 1/8 chance of happening and is the first time I have ever managed to spawn one!

(I didn't notice until after I took the screenshot that I was taunting the little chicken with its mothers burnt carcass....)
