We are raising layer chickens for the first time this spring and got our chicks from the feed store this week. We found the little chick below (the light yellow) in our box of RI Reds when we got home, and I'm not sure what she is? I assumed at first she was a leghorn, but then started wondering if she was maybe a Cornish Cross. Just want to confirm she is a laying breed! I would appreciate any thoughts. Thanks so much!
