This is a normal chicken comb.
This is a frost bitten chicken comb. Chickens get frost bite easily on their combs, feet and wattles.
Her feet look like this. It doesn't cause her difficulty at all. She just use her wings for balance more then a normal chicken. Tomato is our nicest chicken here on the farm, she loves to be pet and cuddled. If someone ever says that chickens are just birds, refer them to Tomato!
