yeah, wild chicken duck and magpie nests. give em a rare chance of spawning where said birds do. with chicken nests spawning under a hen that sits on them, duck nests spawning in shallow water made of kelp, and magpie nests spawning in trees which need to be climbed with your agility skill to get em. if you suck too much you fall on your ass.
make the magpie eggs small so you need 2 to equal one of the other bird eggs.
while we're on the subject, we ever gonna get the ability to raise ducks?
and obviously, these should be rare enough that you need to be raising chickens for consistent eggs. make the nests themselves a curio while your at it.
