Add raw & cooked chicken to /shop (for selling spawner drops)

Chicken spawners exist in the vote crate, but are not currently obtainable since voting doesn't work. If chicken spawners exist next season, it seems strange that you can sell eggs, and feathers, but not the raw/cooked chicken. I think it would be nice if chicken was added so it can be sold. (just make sure if you add this it's balanced)
