ELI5: What happens when a double yolk hatches? Do you get twins?
gpt
Could in theory become two very runty chicks if they made it, in practice they'll unfortunately likely die as not enough space and nutrients to support both of them.

Also, just to clear this up: double yolk eggs happen naturally in about 1 in 1000 eggs, there's nothing genetically engineered about them.
