This summer I was surprised to see a young female (born in 2010) that laid her first eggs at such an age. I was very curious to see the result. Everything went smoothly but after seven days I noticed that one egg was clear (no embryo) and the second seemed fine.

At the expected hatch date I was looking forward to see the chick but nothing happened. The delay was 2 days so I broke the egg. There were two chicks inside the egg and I was shocked to see that, knowing that the chances of such a thing are about 0.01%.

Did anyone have such cases but in which the chicks survived? Can anybody explain this? Is it because two male sperm cells enter the female cell?
