There are some animal sources of vitamin C but that is usually the liver since most animals synthesise their own (unlike humans which need to supplement it). This is why we need to eat fruits and vegetables to get our vitamin C since most of us eat muscle meat which is not a good source of vitamin C. An egg which has not been developed will not have any vitamin C as it is not yet a living creature and does not need or synthesise it's own. A cow's milk has no Vitamin C since cows synthesise their own vitamin C, but human milk does contain it since we do not and our babies will need the supplemental vitamin C.
