I can't hold my breath. I have the hick-ups. Lol. Anyways, I have thought about this question before and I have come to the conclusion that the chicken came first because the egg wouldn't be able to stay warm enough to hatch. If it was in some hot tropical environment and did hatch, it wouldn't have a mate. That means we wouldn't have chickens on the Earth today. It's always which came first the chicken or the egg? If there was more than one egg don't you think it would be which came first the chicken or the eggs?
Also, if the egg did hatch the chick wouldn't have a mom or dad chicken to show it what's good to eat or things of that nature.
