Wild Crops (as their own items)

Crops should grow in the wild as wild crops. For example a Wild Wheat plant or a Wild Carrot plant. These could be smaller and fill up a quarter of the amount the normal wheat and carrot does. Also, you'd need 4 wheat in each slot to make 1 bread, as it is 1 quarter the value of normal wheat. When harvested, their is a small chance that a normal crop will come out. Ex. When you harvest Wild Wheat their is a 2% chance it drops regular wheat on normal mode (just an example, no need to use that specific one.) Also zombies won't drop carrots, and grass could have a small chance to drop wild wheat seeds instead of normal seeds. 

The crops could develop in different biomes, like wild carrot in swamps or wild potato in plains, etc.
