Can I hatch eggs treated with dewormer?

[Altairsky]

I never dewormed my flock and at this point I was just waiting for worms to appear. Yesterday was the day; I saw a white worm swimming like an eel inside a mucous poop my favorite hen just dropped.
So I treated my whole flock with Levamisole.
According to the instruction, I have to repeat treatment in 12 days and the eggs will be bad for 12 + 12 days at least.
One of my hens is about to go broody, should I let her hatch good eggs from before the treatment (but they might be 2-3 weeks old) or are "contaminated" eggs good for hatching (new eggs but from after the treatment)? Anyone has experience?

I'm not sure how many of us you'll find that can speak to treating our chickens with dewormer and hatching eggs, but I'm sure it happens a lot. I can say I've hatched eggs when they were laid after being treated with Ivermectin twice, 10 days apart (SLM). I never noticed anything.

Levamisole, like most dewormers, works by paralyzing the worms.

The withdrawal period is due to the possibility that residue from the drug could be in the eggs.

I'm not finding anything saying would harm hatching eggs.

I know I'd try it.

You could mark the eggs that you know were laid after treatment and see if it actually matters.

Thanks! I'll do 50/50 just to be on the safe side!

Withdrawal periods are for eating/food only, not reproduction. Levamisole is considered safe at label doses in pregnant cows, your chicks should be fine.
