White meat is white because of
the chicken's lack of exercise. White muscle is suitable only for
short, ineffectual bursts of activity such as, for chickens,
flying.
Dark meat, which avian myologists (bird muscle scientists) refer
to as "red muscle," is used for sustained activity, mainly
walking. The dark color comes from a chemical compound in the
muscle called myoglobin, which plays a key role in oxygen
transport. That's why the chicken's leg meat and thigh meat are
dark and its breast meat (primary flight muscles) is white.
Other birds, such as ducks and geese, have red muscle (dark meat)
throughout.

Touching Birds and Eggs Myth
Many of us have heard that
handling a baby bird or bird egg will cause the parent birds to
reject it.
Most birds have a very poor sense of smell, so they are unable to notice human scent on baby birds (even a skunk’s spray doesn’t seem to bother many types of birds). In most cases, even if the nest is destroyed by wind or other means, you could create a new one and put all the nestlings back in it and the parents wouldn’t care that their baby birds were in a different nest when they come back; so long as the new nest near where the old one was so they can find it.

Ducks and Hoopoe will often poop on their own eggs with particularly smelly discharge to discourage predators from eating them.
