I always find worming the hens to be a bit hit and miss, mainly due to the confusing dosing instructions. Confusing that is if you have a small flock of birds who (thankfully) don’t get through the advised 100kg of feed within 7 days.
I buy the 240g tub of Flubenvet Medicated Premixture 2.5%. Flubenvet seems to be the wormer of choice in the UK and is effective against all stages of gapeworm, large roundworm, caecal worm, hairworm and gizzard worm. Apparently there is also a 1% version available now to small flock owners, but this big tub works out cheaper in the long run. Please check which one you have before following any of my imminent ramblings!
According to the instructions, 120g medicates 100kg of chicken food which needs to be fed over the course of 7 days (with any leftovers being disposed of). I estimate that my hens get through 10 kg of feed a week. ‘120g into 100kg feed’ equates to 12g into 10kg of feed. Simple huh?
My 14 hens need 12g of Flubenvet 2.5% fed over a week therefore…
Each adult laying hens need 1.2g of Flubenvet 2.5% over the course of 7 days.
The next tricky bit comes as ducks aren’t listed as one of the birds this mix is designed for. My ducks have access to the chickens feed hopper, so I can’t medicate the regular feed.
Therefore, I shall medicate the chickens afternoon ‘sweeties’ (corn).
1/2 level tsp of the powder weighs 2g, so I need to mix 1 level tablespoon (or 3 x level teaspoons) into their treats.
For this I measured out 7 scoops of corn into a bowl. I sprayed it with oil to make the powder stick and mixed it all in. Just one scoop of their afternoon treats will keep worms at bay.
I will never have to look at that pot whilst scratching my head in utter confusion ever again!
To save my blushes, please someone else admit to being confuddled by the dosage instructions. Surely I’m not alone?
