How soon can a change in chicken food / diet affect the taste of the eggs?

I've just fed my chickens quite a bit of grilled salmon scraps and skin (infused with spicy marinade). They absolutely loved it.
However, I will have guests visiting me soon and they're looking forward to tasting the orange-yolked free range eggs that I just started collecting.

Many people have noted that the eggs can taste awful when their chickens eat onions, garlic, or other smelly food. I personally love garlic and onions, and wouldn't mind my eggs pre-seasoned.

I've seen the videos of hens getting processed where many yolks have already formed inside the body that have not been laid yet.

I wonder how soon the salmon feast will affect the taste of the eggs? I know the guests don't like fish, so I don't want to put them off with fishy tasting eggs. Also, I would assume that the taste difference will be more evident on the yolk than the whites - would that be correct?
How soon will a new diet affect the taste of the eggs?

Never heard how long a feed can affect eggs, but with medicines the withdrawal period is usually two weeks for the traces to be out of their systems. That's my two cents maybe someone has the two dollar answer

I would think that any effect would be seen within 24 hours of the last egg. I doubt that it would last more than two eggs. I haven't experienced the chickens' eggs tasting different based upon diet.

If you google for "Chicken ovary oocyte" images, you can usually see about 5 good sized egg yolks around the ovary and a soft unlaid egg on its way out near the cloaca before the hard shell gets formed. I've noticed that when I've changed the chicken feed to a different brown layer brand, the shell color got deeper within 24 hours, but I'm not sure if the effect would be as immediate for the yolks or the whites. I suppose whites would get affected sooner, but I'm not sure if egg whites taste different anyhow (other than the difference in the freshness)? Based on the photos of the internals, I'm guessing the yolks may be significantly affected in about 4-5 days? I might have to conduct a test (give my chickens stinky food, such as loads of onions and garlic), but would love to hear from people with experience.

I also found this very interesting article. Could it be that we actually suffer from a placebo effect as far as the taste of the eggs are concerned?
