Description
1. The gastrointestinal (GI) emptying of the chick embryo was studied in days 19 and 20 of incubation using radioactive (14C‐PEG‐4000) and coloured (Evans Blue dye) tracer markers.
2. Following administration by oral cannula, the percentages of tracer marker recovered in the yolk sac and the GI tract showed the existence of a GI motor pattern in both 19 d and 20 d chick embryos and suggested that the fluids drunk by the chick embryo during the final days of incubation could have reached the yolk sac from the GI tract via the vitelline diverticulum.
