Fun and charming. I really like how the goal with painting the eggs is more implied to the player through the books, rather than just some given instruction.
Weird bug: I had dropped the empty box of scraps outside the coop while feeding the chickens, before getting the eggs, and when I did get them, they were teleported into the box and not inventory. I was somehow still able to paint them, but not boil them, until I went and found the box, which was not listed as an object in that area. Maybe consider making box un-droppable?
