Notes:
Summary Yolk sac resorption, with special reference to the role of the vitelline stalk, was studied in young post-hatched chickens (0, 1, and 2 days old) using a radioactive (14C-PEG-4000) and coloured (Evans Blue) marker injected into the yolk sac lumen of conscious birds. When the animals were newly-hatched and 1 day old, the radioactive material was recovered from the lumen of the gastrointestinal tract, but not when the vitelline diverticulum was tied. These results suggest a role played by the vitelline diverticulum in the removal of vitelline contents during the first post-hatching 48 h of chick life.
