You can find all the egg information in this post. Love your chickens. Do you think the brown shelled eggs are better than white? They cost more but I am not sure if they are better. I heard that the color of egg shell is from the color of the chicken. Brown chicken lays brown eggs.
I don't know either if the color has an impact on the taste or the quality. But it is true that for example, that a brown chicken lays brown eggs while black chicken lays lighter eggs.
