Birds absorb sunlight through their feathers. It's a must for healthy feathers.So humans make Vitamin D via sunlight hitting their skin. However, birds are covered with feathers, with the exception of their small faces and combs/wattles, so I'm curious if chickens manufacture Vitamin D at all, and if it is related to sunlight exposure in their systems.
Really don't know the answer, but since chickens and humans are really pretty different, beginning with feather coverage for one, and not for the other, I'm interested to know.
