I just wanted to let all those concerned that I have found a site pertaining to grain free feeding. Due to allergies, I have been looking for a method of feeding corn, soy and gluten free. I don't have my chickens yet but have been researching for a couple of years and will FINALLY be getting my chicks in the spring! The site is called "hopecentric" and is pretty interesting. I will definitely be following her. Thought there might bed others out there with the same concerns.
