Thank you for putting in the time to make a cheat sheet for us. I save it all just in case.

Forgive this old lady. I meant poultry dust is usually (0.25%). I tried to get a picture but it was kind of blurry.

You are correct on the spray. It is usually (0.5%).

This is so useful, thank you! Any chance you could provide links to recommended brands that are available on places like amazon? I tried looking it up and got a bit overwhelmed with all of the options.

I think I found a couple of good ones, (this? this?) but since this is so helpful already, adding some links to trusted products of various strengths might be super useful to future chicken keepers too.

I buy the concentrate and mix it with water at the 0.5% ratio. I don't think brands matter so much as the strength of the concentrate.

Fair point! The concentrate seems like the way to go, much easier to buy, haha.

Do you just use a regular spray bottle like these to spray the mixture? Or do you suggest using something else?

I use a backpack sprayer but I have a lot of coops and when I treat one coop I treat them all. Before I got the backpack sprayer, I used a gallon sprayer with a wand. That way I could reach the hard to reach areas with the wand.

I only have 8 hens. So how many teaspoons do I put in a quart of water to spray on each hen?
