Q & A

Below are some recent questions we've received regarding Flubendazole 1%, including answers from our team.

14 April 2022 at 9:15pm



Hi, I have a bantum who I'm sure has gapeworm, the flock has just had 7 days treatment of flubenvet pellets but she is still gaping, would this work and could we dose again so close to the previous?

  • VioVet Staff

This product is only licensed for 7 days of treatment. If your bantum is still showing signs of gapeworm after this course then it is advised to contact your vet to diagnose the problem, any further use of the product will be off license.
You can repeat treatment in 3 weeks time according to the datasheet however it is not advised to wait this long if your bird is still showing signs of abnormality.

Shelf life?


Approximately what is the use by date of this wormer? Or how long is the shelf life once opened- trying to work out if it is a viable alternative to buying in pre medicated feed. Thank you

  • VioVet Staff

The specific expiry date of this product will vary depending on what our wholesaler send us, we unfortunately cannot predict this. The expiry date does not change even if the product is opened as long as it is stored as per the packaging storage requirements. Once mixed into feed then the shelf life may vary so mixed food should be used for treatment straight away.

How often should chickens be wormed?

Marnie Fewtrell

Using this medication, how frequently should you worm the chickens?

  • VioVet Staff

This depends on how you keep your hens. If allowed to graze outdoors then they can be infected with worms from the soil/pasture. It is advised to check for worms every 6 months using a worm egg count kit, such as the Wetsgate Labs Worm Count for Chickens. If positive then you should worm your hens once, and then again 7 days later if on the same ground. This is because they will reinfect the soil after worming. The 2nd dose kills any worms in reinfected birds.

If your hens are kept solely indoors or not on soil/pasture then you could worm them only on arrival and clean effectively. This should clear any worms from their previous residence.

Does Flubendazole 1percent treat capilliaria in hens?


how much would be required and how much food? there are 8 average size hens (Warrens)

  • VioVet Staff

Yes the active ingredient Flubendazole is effective against Capillaria spp. amongst other species of worms. The product is mixed into the feed as per the datasheet at a rate of 6g per 2kg food. The average hen consumes between 100g and 150g of feed per day so one tub for a 7 day course can feed up to 28 hens. This is more than enough for your hens. Your hens will eat the correct amount of medication if you administer it into the food as advised on the datasheet.

Directions for use



As we have a flock of 6 can we syringe the wormer to each chicken directly? If it is mixed in the food I’m concerned we would not know for sure that each hen had their fair share


  • VioVet Staff

The Flubendazole doseage is based on the average feeding rate of a chicken. Those that weigh more and need a higher doseage will naturally eat more of the medicated feed and so receive a higher dose. I do not advise dosing using a syringe as this can actually be less accurate than medicating the feed as it is not flubendazole's intended use. I advise following the administration guidelines as follows:

Chickens & Geese Turkeys
Feed Flubendazole Feed Flubendazole
20kg 60g (10 scoops) 30kg 60g (10 scoops)
10kg 30g (5 scoops) 9kg 18g (3 scoops)
2kg 6g (1 scoop) 3kg 6g (1 scoop)

Mix Flubendazole thoroughly into feed for even distribution. Only use the medicated feed for the 7 day treatment period.

Ducks and treats?

Michaela Black

We have chickens and ducks, can this be used for both? Is it easy to work out how much to use for multiple birds at a time? Do you have to withdraw treats and how long for?

  • VioVet Staff

This product is licensed for use in chickens, geese and turkey. It can be used off license in ducks but as it is an off license use then I cannot advise on specifics of treatment. I recommend contacting your local vet who can discuss this with you.

The doseages for chickens can be found in the data sheet itself. Once mixed into the feed it should be the only food fed to ensure enough of the product is ingested.

Does this treat and kill gapeworm in my chicken ?

Lucy Diciancia

Does this kill gapeworm? And is it the same as flubenvet are the ingredients the same

  • VioVet Staff

The active ingredient in this product is flubendazole, exactly the same as Flubenvet. The only difference is in their brand names. Flubendazole is effective at treating Gapeworm in chickens.

What is the minimum age of chicks that this can be used on

Paul Symons

I have reared some young chicks and they are in a run on my veg patch being used as part of my pest control. What age should I consider worming them and is this the correct product? Yours Paul

  • VioVet Staff

Yes Flubendazole is the perfect wormer for your chickens. There is no minimum age for flubendazole, however you should not need to worm until your chicks are at least 12 weeks old. I would consider getting a faecal worm egg count test done, Westgate Lab Worm Egg Count For Chickens is a good choice. The results of this test will let you know if you need to worm or can monitor and retest in 3 to 6 months.
