Vitamin K

Vitamin K is also essential in healing from minor and major internal and external injuries. A delayed blood clotting process on any injury may arouse other chickens’ cannibalism interests.

A deficiency of vitamin K can result in devastating internal bleeding and red blood spots inside the egg

Vitamin C
