Q: The whites of my chickens' eggs are a funny color--what does that mean?
A: Cloudy whites in a farm egg are usually indicative of its freshness. The cloudiness is caused by dissolved carbon dioxide in the white, which eventually escapes through the shell in older eggs. If the white of the egg is greenish, that usually means there is too much riboflavin in the diet. Make sure they are getting balanced nutrition. Eating acorns, shepherds purse or some types of weeds can cause that greenish tinge, too. Pinkish whites are caused by some types of weeds a chicken may get into, or high quantities of cottonseed meal in the diet.
