Fall Deworming - Ivermectin? Dewormer in the water supply?

[casportpony]

@casportpony Thank you for the info. A mash deworming might work since I do feed fermended feed. If you have info on that it would be most appreciated.

The de-wormer I will us as an example is Valbazen (albendazole 113.6 mg/ml)
According to a study I read, the most effective dose is 20 mg/kg, which is ~0.08 ml per pound.

1. Count the number of birds to be treated.
2. Estimate the weight of each bird (look up breed weight on the web and use those weights).
3. Calculate flock weight. For example, if you have 10 leghorns at ~4 pounds each and 10 RIR's at 6 pounds each, that's 100 pounds of birds.
4. Calculate the amount of Valbazen needed. In my example it's 100 pounds (weight of flock) divide by 2.2 (this converts to kg) times 20 (the dose needed) divide by 113.6 (the amount of medication in one ml) = 8 ml to treat the flock
   100 ÷ 2.2 x 20 ÷ 113.6 = 8 ml
5. Set aside the amount of pellets or crumbles they will eat in a day in a big container.
   
6. Mix the 8 ml of Valbazen in some amount of water, two cups maybe? Add the water/Valbazen mixture to the crumbles, stir a little, then add more water until the feed is nice and wet. Mix *very* well.
7. Repeat in ten days.

I've tried searching for dewormer info, especially in water, but I get crazy return results so I hoped starting a thread would target the info better.

As I see it, the main problem with the water method is that not all birds drink the same amount of water. Some only drink 5% of their body weight per day, while others might drink almost 20%. So, for example, if you put 1000 mg of something into a liter, the 1 kg bird that drinks 5% will get 50 mg, but the 1 kg bird that drinks 20% will get 200 mg.

Of my 12-18 mos old birds, 1 is moulting now. The rest are done or not headed there yet.

With only one molting I would still use the Valbazen.

Wow. I didn't meant to start a wee stramash!

It's a hot topic, lol.

Thanks very much @casportpony. I will try that method. I create a fermented mash each day anyway so this should work great! My old Plumb formulary doesn't have much on dosage info for chickens since it seems there aren't many things officially approved for use in chooks.

Where do you get your Valbazen @casportpony? I'm looking online and it's gonna take a good long while to use up 500ml (the smallest I've found so far) a few mls at a time for a small flock.

Here are some formularies that I use:

Tons of good stuff here, especially for vet techs and vets.

My old Plumb formulary

Which one do you have? The 6th edition is online here:

Attached is another formulary I refer to.

A friend gave me the bottle, but if I were going to buy it I would get it from Jeffer's or Valley Vet. Your other option would be to use Safeguard for goats but it will be more expensive because you have to give more of it and it has to be given five days in a row if you want to treat capillary worms. If your 15 birds weigh 5 pounds each the formula looks like this:
15 x 5 / 2.2 x 50 / 100 = 17 ml per day
17 x 5 = 85 ml
The smallest bottle of Safeguard is 125 ml and costs $22 to $30 depending on where you get it.
