I guess a lot of people know the difference, but I don't... I have two of these girls and they are GORGEOUS!! My dad went back to school (and I'm so proud of him!) for horticulture and one of the girls in his class is moving to DC so she gave us 10 already laying hens, a chicken tractor, 65 egg cartons, and some feed FOR FREE! These ones were in that bunch. She didn't know what they were.
