@bigchick relax, don't worry about yolk colour.....
www.en.m.wikipedia.org/wiki/YolkYolk color
The color of an egg yolk is directly
influenced by the makeup of the
chicken feed. [16] Egg yolk color is
generally improved with a feed
containing a large component of
yellow, fat-soluble pigments, such
as the carotenes in dark green
plant material, for example alfalfa.
Although much emphasis is put
onto the color of the egg yolk, it
does not reliably reflect the
nutritional value of an egg. For
example, some of the natural
pigments that produce a rich yolk
color are xanthophylls without
much nutritional value, rather
than the carotenoids that act as
provitamin A in the body. Also, a
diet rich in vitamin A itself, but
without A-provitamins or
xanthophylls, can produce
practically colourless yolks that
are just as nutritious as any richly
colored yolks. Since unhealthy
chickens produce fewer and
smaller eggs, farmers ensure that
whatever the source of their feed,
the quality is adequate, so there
is not likely to be much difference
in the nutritional quality of the
eggs. [17]
Yolks, particularly from free-range
eggs, can be of a wide range of
colors, ranging from nearly white,
through yellow and orange to
practically red, but even olive
green, depending on the pigments
in their food. Feeding fowls large
amounts of capsicum peppers for
example, tends to result in red or
deep orange yolks. This has
nothing to do with adding colors
such as cochineal to eggs in
cooking.[18]
