Since this isn't taste-o-forum we cannot tell how they taste. This may help, a friend of mine told me her husband doesn't like the taste of the fresh eggs: he buys store eggs
so he mixes them together. He says they are too strong, whatever that means.
They should have a nice egg flavor, and I find them to be very "buttery" not that they taste like butter it is the creamy texture. They are also very firm and stand in the frying pan, they look like hocky pucks, standing at attention.
I think if they were bad you would really know it.
Don't worry I am sure they are ok.
By the way my friends are also frizzle polish, maybe there is something to this, I have a mixed Polish and her eggs are a bit strong but I have nothing to compare them to. I will soon I hope.
I guess we are not helping, sorry.
