Roundworms!!!

[chickydoodles]

Too late to save her? What are her symptoms?
Did the vet give you any worm medication?
Where are you located in the world (state/country)?

If you are in the US, I would use either Fenbendazole (Safeguard) or Valbazen to treat the whole flock.
I've only found Valbazen online, so if she is sick it would be better to get the Safeguard at Tractor Supply and begin treatment. Get the smallest syringes you can find.

Fenbendazole (Safeguard) dosage is .23ml per pound of weight, give orally for 5 days in a row.
This shows you how to administer medications https://www.backyardchickens.com/ar...er-construction-check-back-for-updates.73335/

I know this is an old thread but I’m treating my flock for roundworms and I have a question about dosing. Everything I’ve found online says to dose on day one and then again 10 days later. Why are you saying 5 days in a row? Also, isn’t a second dose necessary due to the life cycle of the worms?

Welcome To BYC!
Fenbendazole treatment for Roundworms Only is to give 0.23ml per pound of weight orally once, then repeat in 10 days.

If you are wanting to treat other worms including Roundworms, but not tapeworms you would give 0.23ml per pound of weight orally for 5 days in a row. Repeat is not necessary when giving the 5 days in a row.

Ah, ok. This makes sense. Would you mind looking at a pic and giving me your opinion about what type of worm I’m dealing with? I’ve only found two, in two different poops. They are the shape of roundworms I’ve seen in pics but a lot smaller.

Do you know the approximate length? Since you've seen large roundworms, they can grow up to almost 5 inches. There are two reasons why large roundworms are excreted (other roundworms as well.)
They are either dead or dying and are excreted in feces. OR, the bird is overloaded with worms and they have nowhere else to go but out the rear end and are excreted in feces. They will die because they cant survive outside the host.
Here's a pic of a cecal worm by comparison, hopefully it'll help you identify what type of roundworm was excreted in your birds. In any case, the Safeguard will take care of both types and other unseen types of worms as well, just do the 5 day dosing.

Hard to tell what they are maybe roundworm, could be cecal worms.
Agrees with @dawg53 in any case, I would treat with the Safeguard and give for 5 days in a row.

First I found was 1/4”, second was probably 1/2”. Both were alive. The pic I posted is a screenshot from a video. I tried to post the video but it doesn’t appear BYC allows videos. I think that would help with identifying the type.
Last question. If a bird has been dosed with fenbendazole, can it ever be used as a meat bird?
Actually, I do have one more question. This chicken has had balance issues and weakness in her legs to the point that she sometimes sits back on her bum. Can worms cause this?
Thank you for your help!

I dont know exactly what would cause your bird sit on her rear, definitely not worms...maybe Marek's disease, I havnt dealt with Marek's .

Identifying what type of roundworms you're dealing with really doesnt matter. All roundworms have the same direct lifecycle, some also have an indirect lifecycle. Fenbendazole eliminates all of them.

In the U.K. there is a zero egg withdrawal period and a 6 day slaughter withdrawal period.
We eat eggs after using Fenbendazole. I dont know about slaughter withdrawal here in the U.S. but I'd have no problem eating the meat.
