There was another egg, properly formed, inside the egg.
“Having two perfectly formed eggs together is just incredible,” Scott said to ABC News Australia.
It was the first of its kind, according to a veterinary sciences expert from Charles Sturt University.
According to Associate Professor Raf Freire, the hen must have normally developed an egg but for some reason chose not to lay it.
He told ABC News, “Then the following day, instead of that egg being laid, like it usually is, what’s happened is that another ovum has been released.”
That has fallen, and the chicken has inexplicably chosen to form a shell around both the egg from the day before and the recently fallen ovum.
Although the experts said that eating the egg would have been safe, Scott told ABC News that they receive 50,000 eggs per day and therefore “didn’t bother eating it.”
