Accidental wormer overdose?

[WindingRoad]

Just happened tonight. Won’t know that till the morning.

Then why fret tonight? I've got nothing ( more)

So... I screwed up! (Disclaimer: long post) I noticed some small thread like worms in some droppings about 3 days ago. I had a little safeguard eqine paste (fenbendazle) on hand and was able to give it to 2 of my 13 chickens. Fatty a barred cochin weighing in at 2990g or 6.5lbs got .6ml and Kate a buff Orpington weighing 2275g or 5.0lbs got .55ml of the safeguard paste. I know! I know! Before I get the spanking of “Not the right dose” here’s why. 3 days ago I found articles/ threads recommending the “pea sized” dose. After researching tonigt, I now found the newer recommended and more specific dose of .23ml per lb.
Anyhow, back to the story... The tube then felt clogged (it wasn’t) and I used a little too much force, basically it ended up in the dirt unusable. Went to the store and got Ivermectin pour-on (the blue topical stuff) instead to do the rest of the flock. I was able to convince a family member to help out tonight to hold each one while I administered carefully measured drops. In my haste at actually having, for a limited time, help for once and exhausted from a 12 hour shift at work, I did ALL of them! Including the 2 whom I forgot already got the safeguard 3 days before! I gave, from what I’ve read, is a conservative 4 drops each to those two birds. As soon as we were done with everyone, I realized my stupid mistake! What have I just done?!? I can’t exactly wash it off! My question is what effect will this have on the two girls who got double dosed if any? What do you think?

@casportpony @dawg53 What y’all think? You guys seem to know your stuff. Please chime in here when you get a chance. What should I do now?

Have a gander at this site:
It's hard to know if the 2 that got double dosed will experience a problem. But here's a great summary of the options available. There are a list of references and additional reading on the topic listed at the bottom of the article. Ivermectin, according to this site, applied topically, will treat roundworms, threadworms, gapeworms and external parasites in chickens.

@BiddyBiddy As mentioned, your birds will be fine. I dont recommend Ivermectin as a wormer. It has lost it's effectiveness as a wormer in poultry due to its overuse in treating mites. As a matter of fact, according to Parasitepedia, it has lost its effectiveness in treating northern fowl mites due to resistance.
I've used Ivermectin Pour On and Eprinex in the past and saw large roundworms in feces 4-5 weeks later, not very effective at all. Stick with the benzimidazoles and leave the avermectins to other livestock and dogs.

Flubendazole (the active ingredient in Safeguard) has an overdose safety factor of 10 X the recommended dose.
Overdose symptoms are diarrhea. The symptoms stop withing 24 hours of zero dose.
Because Flubendazole is often added to feed there is no way in these circumstances to ensure that one fowl doesn't consume more of the product than another. In such cases it is quite possible to have one fowl ingest more than the recommended dose.
Ivermectin will not treat worms.

@Shadrach Just a reminder, the active ingredient in safeguard is fenbendazole.

Okay, thanks.
I think all the benzimidazole anthelmintic de-wormers have a similar overdose tolerance.
Thanks anyway. I'll check.

I've only got the sheet for Panacur which doesn't give an overdose factor.
We use this for the sheep and it's a feed mix rather than a direct dose so I would guess that the side effects through overdosing are minimal.

Yes, you're correct. Flubendazole is a benzimidazole. They are all very safe, but I wouldnt drink a bottle of safeguard liquid goat wormer!
