Chickens eating ivy + toxicity to eggs?

[rubyred]

I've just realized that my green-starved chickens (or at least one of them) have been eating English ivy when they go out to forage now that the weather is a bit better. I know that it's toxic to them and will figure out a way to deal with limiting their access to it, but was curious whether I should throw out the eggs? Anyone have a sense of this?

Thanks!
