I bought 3 Cornish Rock babies at TSC this week and via feather sexing, I think they're all pullets. I'm going to give 2 to my brother and try to raise the third one as a laying hen. My hens get to forage all day around our backyard so she will get plenty of exercise. I just found the chicks SO adorable that I at least want to give it a try. I blogged about it here : http://backyardfarmer101.com/cornishrocks/ Has anyone else successfully raised a Cornish Rock into adulthood as a laying hen? I'd love to hear your experiences.
