Hello, I have a question regarding my Delaware chickens. I purchased 10. Out of that I have two females that don't quit look like the rest. The difference between them is that the are a bit smaller and more rounder plus that practically have no comb. But they are just about the most friendliest of all. Do you think this is a defect of some sort? I am planning on breeding and have a few females that match the description of a Delaware perfectly but these two are just so sweet I thought they might make some cuties also. What do you guys think?
