Is codified copper sulfaste safe for eggs?

[Spruceroost]

I can't find info on this. But I'm treating my chickens with acidified copper sulfate and pomegranate juice to help with canker. Are eggs safe for consumption while they are taking this? If not, what is the withdrawal period?

I will give you my opinion - you will need to do some research/reading to make sure you are satisfied with my answer. Acidified Copper Sulfate (given in the proper dosage) is
"A source of supplemental copper for chickens and turkeys that can used in feed or water". I have also noticed that some feeds list Acidified Copper Sulfate in their ingredients. So....with this being a supplement it would not have a withdrawal period.
