New Item: Feed Sack as an Inventory item
(example image of Irl -

Why:
1. Easier to trade fodder. We have villagers that have some good carrot fields but not much desire for cattle. They can put them in feed sacks to make high quality fodder for trade (can even be put into a barter stand now because inventory item). Maybe it could store 1/4 of a food trough?
2. You can see the avg quality of your feed after its been mixed with other stuff
Just a thought
