Question

Judy asks: What would happen if you incubated a double yolk egg? What would hatch if you incubated them for the 21 days required? Would you get 2 two chickens? Would you have Siamese twins? Some kind of horrid deformed monster? What’s the answer

Answer

Chris Smith put Judy’s question to Maud Borensztein from Cambridge University

Maude - You will end up with two chickens. The thing is even if a double yolk egg is bigger than a single yolk, two chicks won’t have enough space. So having two healthy chicks at the end is something that is unlikely to happen.
