Our three eyases have have grown quickly! All three are well fed and moving around the nestbox. They aren't coordinated enough yet to walk on their feet...you'll note that they waddle on their tarsus. All three are feeding well...following a feeding you'll note a swollen pouch below the chick's neck. This is a storage organ called a crop. It is a essentially an enlarged portion of the esophagus that stores food prior to digestion. It allows the birds to quickly consume a large quantity of food and digest it someplace safe and away from potential predators or competitors.
