This is my first time with this breed. I ordered 1 White Rock with a mix of other calm or friendly breeds but also added a Meyer's Meal Maker. For those that haven't ordered from Meyer's Hatchery, they throw in a chick that you can donate eggs from. So, when I took my chicks out of the shipping box, I could see that I had two identical little yellow ones and deduced that my meal maker was a second White Rock. I've never had this breed but have read they can develop faster than some of the other breeds I ordered. One of the White Rocks' comb stands out to me. I'm hoping it's a pullet. I'll keep you posted. They are only 10 days old now. When I was taking the picture, an EE chick came up and inspected the comb!
