I am new here and have a question about one of my 2 yo Leghorns. I feel silly because I never noticed before that one of my 4 Leghorn hens has yellowish ears rather than the pearly white like the other 3. Is this just a variation of the breed? It isn't any infection, the color is just a yellowish hue. Also, her comb is small and single, not flopped over like the others. Thanks for any information.
