PLEASE help my addled brain!
We have four nice sized Warrens... Our Flubenvet 1% arrived today.. Can someone please work out VERY simple quantities to give them? Is it 6 grams per hen, per four, per day, per week?
I promise I'm not normally gaga but I've had a day of information overload :blink: ![Sad :(](https://chat.allotment-garden.org/Smileys/green/sad.gif)

Hi Jan,
I've lost this thread a bit so if someone's already answered your question my apologies however here's a simple answer to your question for 4 L/F birds using 1% Premix.
___________________________________________________________________________
Measure out 4KG of feed, add two scoops (2X 6grms) of wormer. Mix REALLY well and feed this exclusively for 7 days.
___________________________________________________________________________
WHAT TO DO WITH THE LEFTOVERS
(You'll probably have about 400grams left over which you can continue to feed for a further two days if you like or throw away. Don't add further unmedicated feed on top as you don't want to let them have a weak dilution which might breed resistance in the worms)
HOW THIS IS CALCULATED FYI
Remember 2 facts - they must be medicated for 7 days continuously, and using the 1% Premix the feed medication rate is 3grams per kg of FEED.
So first you need to calculate how much feed you will need for all the birds for 7 days. If you know your birds consumption use that, but if not work on 900grams per week, per L/F bird. So in your case that's actually 4 birds X 0.9kg = 3.6Kg (make up 4kg for ease of using scoop measure).
HOW TO MIX
Using a large container (a trug is ideal) and rubber gloves sprinkle some corn oil onto the pellets and mix well so that the pellets are just slightly darkened but not softened so they disintegrate. The oil prevents the powder settling. Sprinkle the two scoops of Flubenvet powder over the surface in several batches, as evenly as you can, and mix really well as you sprinkle each batch.
If you feed mash don't use the oil but use the mixture in 4 batches topping up the feeder every two days which you should remix each time you top up so the powder doesn't settle out.
You now have 4kg of medicated feed you can fill their feeder from and feed for the week.
HOW TO AVOID BEING CONFUSED
Don't try to follow the rather convoluted instructions provided by Janssen and stop thinking about how much medication each bird needs per day. They will eat the requisit amount of wormer for their weight provided you don't feed them anything other than the medicated feed. So NO treats or unmedicated feed. If they free range it's best to confine them so they don't eat too much unmedicated food. Don't worry about overdosing, Flubenvet has been tested at upto 2.5 times the recommended dosage with no ill effects. I prefer to slightly (<20%) overdose than under.
Hope this helps.
