It is currently unknown what, if anything, hatches out of these eggs.
Behind the scenes
Aaron Sims Creative created the concept art for the egg. The company Fractured FX, who made the prosthetics for Will's fake body and Barbara's corpse, created the prosthetic for the egg as it was seen in Chapter Eight.
