Recent hot weather has been used as an
excuse by some egg producers to put manufactured colouring additives
and meat meal in their poultry rations. (Many others have been doing that for years).
Now more than 95% (and it's probably
99%) of egg producers, even those which claim to be free range, are
using additives to enhance yolk colour as hot conditions have dried
off the pasture on which the hens are supposed to roam.
They have looked for a solution which
is low cost and easy rather than go to the extra effort (and cost) of
supplementing existing feed with green leafy vegetables, pumpkins,
carrots and lucerne meal or sprouted grains.
Here's a Facebook post by an egg
producer which provides an 'excuse' for its decision: “Please
note that we have an immediate change in poultry diet based on
veterinary and animal nutritionist’s advice due to severe heat
stress caused by prolonged 40’C + temperatures.
Our feed ration needs to include soluble meat protein and natural pigmentation (which is the norm in the egg industry). The extreme heat has decimated our green pasture and caused weight loss in flocks and as such we have no alternative but to implement these changes to our farming practices”.

The big difficulty with colouring
additives is that although some may be based on natural products,
they are manufactured in laboratories or factories (often in China)
and concentrated in powder or liquid form. Many of them generate
allergic reactions or sensitivities – which lead people to think
that they are allergic to eggs.
We can provide details about the allergic properties of the commonly used additives.
The use of meat meal is also an issue
as poultry products are frequently used by the feed mills.
