Chicken Types, Characteristics & Uses

For instance, many important discoveries in limb development have been made using chicken embryos, such as the discovery of the apical ectodermal ridge and the zone of polarizing activity.

Chickens are social, inquisitive, intelligent birds, and many people find their behaviour entertaining.
