When a vanilla egg is fired from a dispenser, it turns into a thrown egg entity and can spawn a chicken when it hits a block. Golden eggs fired from a dispenser fall to the ground as an item, as if it was fired from a dropper.

In the pack I'm working on, I want to encourage people to automate magic beans. To do this I plan to tweak the drop tables to contain less valuable loot, and then add a recipe to the magic bean. It's a nice puzzle, but letting them work with dispensers would be more intuitive. It would also be consistent with vanilla behavior.
