    Cool Embryo Development

    What is the mortality rate of a human, and what is the mortality rate of a chicken. Is a chicken precocial and why? Is a human altricial and why? Human young go through developmental stages such as neonatal, infancy, childhood, and puberty...what developmental stages do chickens go through?

    Default Re: Embryo Development

    The mortality rate would be 100% for any individual. It would need to be defined to be of any use, by country, age, from specific diseases, etc.
