The question of the day seems to be: "why are some chicks yellow, and some black?"

Carl:
It's all in their genes which they get from their parents. Just as we humans may have our "mother's hair", our "father's nose", or our "great-uncle's eyes", the chicks have feather patterns they inherit from their parents, grandparents, and so on. The chick's "family tree" is called a "breed". To read about some breeds, check out the Standard Varieties of Chickens page.
