"This hands-on project has lesson plans, activities, and resources. The goal of this site is to increase knowledge about and develop interest in the science of embryology as well as to provide learning experiences in incubation, hatching, and brooding. It also provides cross-curricular objectives and it intends to train teachers to conduct classroom incubation and embryonic development projects."

"Domestic chickens have essentially lost the ability to fly. Heavy breeds used for meat production cannot do more than flap their wings and jump to a little higher level or move more rapidly along the ground. The lighter-bodied birds can fly short distances, and some can fly over relatively high fences. The feet and shank portions of the legs have scales."
