Structural Change eggs, not only that but now instead of leather armor drops armor, along with a chance at a bow, 10 arrows, a diamond sword, a normal egg, and cooked beef. In this mod will drop the golden egg chicken egg throwing items. So far they only put leather armor but may change soon Not only that!
I have more armor stone, which is the same model as the others but made with stones! Check this out. There will be more changes in the future. 13/08/13: I have created armor stone will come from eggs, like other commodities. But, there is a flaw armor so once it's fixed I'll have an update.
Ignore any kind of tampering that said, it does not seem to want to go off
