The yolk, which is mainly composed of fat, is responsible in providing the embryo with the nutrients needed for development. The hen converts part of the feed she consumed into a layer of yolk. The development of the yolk takes place inside the hen and is performed daily until the yolk has reached the required size for ovulation. It should also be noted that during this time more than one yolk is being developed. By providing fat soluble dyes to the hens, we shall be able to see the development of the yolk indicated by the ring/layer colors.
The purpose of the Poultry Club is to help bridge the gap between poultry students and the poultry industry.
