Embryo vs Fetus. Embryo and fetus are different stages in the human reproduction process. The human life starts when the sperm and ovum (egg) get together to form the fertilized ovum. Fertilized ovum starts to divide and produce more cells. When it starts to divide in to two cells, 8 weeks from fertilization, the period is called embryo period. The dividing cells collectively forms the embryo.
Like humans, chickens regulary ovulate. Like humans, chickens expel non fertilised eggs. The difference between chickens and humans is that humans will keep a fertilised egg in their body until birth. Chickens will expel both fertilised and unfertilised eggs, and only sit on the fertilised ones. I don't know if, when a hen expels an unfertilised egg, if there is fluid accompanying the expulsion.
