This may be a really stupid question, but I raised canaries for years, and I was wondering if you can (or need to) add beta-kerotenes to the chickens' diet to enhance the red color? I notice that a lot of hens and roosters wattles and combs are very faded - almost not red anymore...and I wondered if that was because this was missing from their diets - so I'll know what to add to my chickens diets if they fade.
Thanks for your time!
