On March 20, I bought what was labeled as 10 "cornish rock" hens. Thinking that they were cornish crosses (they did have the meat bird label on their tub) I prepared myself for my first batch of chickens meant solely for processing. Well, the ended up NOT being meat chickens. In fact, not only are they not plump and fat but they are still flying. So, I'm thinking that they may be white rocks instead but here is the thing; they all have ROSE combs rather than the single comb that I see in all of the pictures. Is this possible?
