About half my flock are EE, halfish are Black Aus, and five are Brown Leghorns (white eggs). Other than color, I have no idea who lays what, but I have no egg issues. They get straight all-flock pellets, a handful of scratch once a day when we turn tem out to forage so we can look them over, and have self-serve OS and grit always available. They are one and two years old. There are 20 of them and we get 12 to 16 eggs a day, even in this heat. Good luck with yours!
