Ivermectin Dosage for Chickens and Water Fowl

[CajunPeeps]

I just discovered my seramas have lice and one I recently purchased in a pen by himself has leg mites. I dosed them all with ivermectin pour on for cattle. Questions:

When do I dose again?
Can 6 week old chicks be given ivermectin? (They are in a brooder in same room as seramas.)
Is it safe for call ducks? They are in a seperate pen in same room. I gave them each a drop.
How much is too much? I gave 9 seramas, that were supposed to be wormed a week ago a drop or two of ivermectin. They are new and not sure what they were wormed with. They are seperated but did see bugs.

What else should I do? These birds are all in off the ground pens in a large screened in room.

I'm not familiar with Ducks.

With my bantys, I just give them a single drop. Not sure what the age minimum is, as long as they have feathers and the dosage is small I think you'd be good .

I don't think you can give a chicken too much by just using drops. Of course, for bantys ten drops would be too much, the one drop is probably good.

Lice are best treated with permethrin dust or liquid (Permectrin II) or Sevin dust used every 10 days until nits or eggs are no longer seen. The coop and nest boxes must be cleaned out, treated, and replaced with new bedding. Here is some reading:
