Having moved from GTA to 1 hectare property west of London, I decided I could raise a few back yard chickens. I got nine chicks last summer, lost one to a predator, watched them grow, and started to get eggs late last fall.
They provided (daily) beautiful fresh orange-yolk eggs with good shells. The birds were outside on the grounds every day until a cold snap in January. I was puzzled by the lack of change in the fresh yolks and firm whites from the winter eggs. I called the feed company, and they quickly confirmed that they do not use orange additives such as carotene, but the color and flavor
are due to corn as the major ingredient.
I believe you can find eggs with orange colored egg yolks from the major Ontario producers, Gray and Burnbrae. I know I have purchased them from Highland Farms, and they were not Omega 3, but something labelled 'naturally fed'.
They should be available in many stores. Many of them will come from humane small operations, but this is difficult to say, and we need to keep pressure on Gray and Burnbrae to watch their suppliers.
To get a good batch, they have to be very fresh, perhaps less than 7 days from the nest. You can tell if there are three distinct layers when you break them into a pan.
I'll come back to this this thread in a month or so after my hens go out on grass. They will still get Shur-Gain corn based feed, but the yolks may change a bit.
