Flubenvet Wormer

  • 1% » 60g Tub £28.29

We can supply Flubenvet for chickens which are not kept as a commercial enterprise and it is the ideal worm treatment for "back-yard" birds. It is safe to eat eggs from treated birds even during treatment. Flubenvet kills worms and their eggs and is a sensible measure for any previously untreated free-range bird which is showing non-specific illness, or where worms are diagnosed or suspected.



The amount of Flubenvet used is based on the weight of the feed, not of the animal. For example, 60 g of product (the whole tub) medicates 20 kg of feed. See below for more information.

Flubenvet is provided with a handy small scoop so that the correct amount can be added to food. Treatment is normally continued daily for 7 days, then repeated 3 weeks later. Free-range chickens should be kept in as large an area as possible, for welfare reasons and to reduce the parasite build-up on the ground. Moving the birds to a fresh area is also a big help, and ideally is combined with a worm treatment to help keep the new ground clean.

Our girls have salad everyday as well as their layers pellets. Will they still be able to have their salad or only their medicated pellets ? Thank you

  • Non-Executive Director

It is more effective if you only provide the medicated feed while treatment is being given. That is what I would have to suggest just for this time.

Worms treatment

My chicken s are kept in a run do I need to use wormer

  • Marketing Analyst

Yes, it is important to worm your chickens for prevention or cure. As long as they are kept for Noncommercial purposes only.

Worms can cause all types of problems in chickens such as weight loss, increased seed consumption and in severe cases amnesia.

It's important to worm regularly and ensure that the appropriate procedures are carried out in the environment they are kept to kill any worms in the soil.

Flubenvet will help kill worms and their eggs. It is recommended to worm chickens with Flubenvet every 3 weeks.


Is flubenvet suitable to use with ducks?

4th Sep 2015

Hi ive got runner Ducks with my chickens that share the same food, is it safe to use flubenvet on them aswell as the chickens please?
Also I was told about a stronger % flubenvet product possible 2.5% is this something that is available do you know? Ive got 31 chickens and 10 ducks.
How long do you dose for? & how often should I be worming please?
Regards Jen

  • Non-Executive Director

Flubenvet is regarded as a safe and effective wormer for ducks. It is normal to feed for one day to give a worming dose and this should be repeated at least twice a year, depending on how crowded the birds are and if there are young birds present (which tend to suffer more with worms). Frequency of worming requirement will always vary from one establishment to another so fixed recommendations cannot be given. Best to talk to your vet about this if you are not sure. The larger size of Flubenvet is only available for commercial flocks due to rather odd legal restrictions.

Does the product work?

ezaisting problem

I think my chickens already have a worm infestation. Is this product effective at eradicating an exsisting problem? Also would you recommend use of a sanatising powder on the ground if moving to a new location isn't possible?

  • Non-Executive Director

Flubenvet s very effective with a pre-existing worm burden, but of course you are right and the ground will be contaminated with worm eggs, so re-infestation will occur. Moving ground at the time of worming would be best, but often is not possible. Maybe you could put down a clean surface, such as fresh straw, or a new layer of topsoil. Sanitising the ground would be fine if you could do it effectively, but I am not sure that this is truly possible without using something more toxic than you would choose.

How long does this medicine keep for? You are out of stock of the 60g tub which is the size I require, but wondered if its worth buying the larger pack and using next worming period?

  • Non-Executive Director

This is a good question but we have no specific information on this. As a general rule, when a sealed container of medication is opened, the contents are best used up within 1 month and the rest disposed of. In fact if the product is used and stored carefully, so that moisture is kept out and it is sealed and stored at appropriate temperatures, then it will keep for much longer. The unopened use-by date is often 2 years for this type of product. Our current stock has an expiry date of February 2016.
