Chickens.
We raise multiple types of chickens. Hatching a and raising Araucana (Easter Egg Chickens) which produce light blue and green eggs, and Rhode Island Reds which produce brown eggs, Pioneers for eggs and meat.
Despite what people claim, the color of the shell does not change the taste of the egg. Eggs flavor and yolk color is a direct response to what the chickens eat. Bright yellow yolk, which are common in farm raised eggs are caused by large percentage of corn in the chicken's diet. We use a combination of corn and pelleted feed specifically formulated for egg producing chicks.
