Hi, I have a mixed flock of 4 hens: 2 Belgian Duccles (about 1kg each), an Isa Brown (~2kg) and an Australorp (~3kg). The Isa Brown in particular has been showing issues with laying and may be underweight. Otherwise she seems fine, active etc
We have been getting a lot of smaller wild birds into the run lately so I am worried about worms. They haven't been wormed for a while.

I have some arisotpet chicken wormer and want to worm them but am unsure of the dosages. It states basically 8ml/100ml of water for every 3kg of weight.

I have about 8kg of chickens. Does that mean I just mix up about 300ml of water with 24ml of wormer and let them at it? Doesn't seem right.

Otherwise I can separate the larger two from the smaller two. In that case would it be 8ml/100ml for the larger and around 4ml/100ml for the smaller hens, and make sufficient volume of each to last the day?

Just not sure what to do, any help appreciated.
 
I'd suggest following the instructions. I guess the treatment does not have to last a full day -as long as they have the required concentration of the treatment, it should be fine.

It gives dosage instructions on this link, including to withhold water 2 hours before bedtime, then putting medicated water out at night so they will drink it first thing in the morning continuing for 8 hours. You need to mix up the amount your chickens will drink in 8 hours. It's bascially the same concentration, no matter what each one drinks--they will drink the correct amount for their weight (ideally.)

I have no idea how much they drink, I just refill their water as required.

So it looks like I just mix up a batch of say 500ml with 40ml of wormer.

Thanks for the replies.
