As the laying cycle progresses and birds get older, there will be some changes in the eggs as well.
In addition, you might see unexpected differences in the physical qualities of the eggs, caused by stress, disease or changes in water or feed quality. Knowledge about the different signals can help you to use your management skills to handle things well.
