Shearing chickens and Mudballs for pvp or even pve

First off you should make it so you can shear chickens so you don't have to kill them for feathers.

You should also add a second drop for the pig because cows have leather, sheeps have wool, and chickens have feathers.

So maybe you can have it so a pig wallows in mud and then you can shear it or kill it to get a mudball or something and it works like snowballs except it slows the thing that got hit.

The mudball could also limit the players view and if you throw it at a mob they won't see you at all if your sneaking.

I feel like these would be really cool additions and also make the chickens a little happier! :)
