I tested it myself, I went on ebay and ordered a chicken and a dozen eggs, the eggs came next day, the chicken two days later.
Genetically speaking, the egg came first. Something VERY close to a chicken laid the very first egg that a chicken came out of.
This is an oxymoron
Ahh, the internet.Or, perhaps something very close to a chicken birthed the first chicken. Or created a mutant chicken through fission.
