Double dosing a roo with ivermectin ?s

[gritsar]

I wormed my whole flock the other night including my roo, with ivermectin.
I still need to do something about my roo's swollen feet. A "chicken doctor" told me it was scaly legs mites, even though it's not a classic presentation of scaly leg mites.
I've tried just about everything else - vaseline, etc. - with no improvement.
I want to try using ivermectin mixed with oil and paint his legs with the solution.
How long do I need to wait to use the ivermectin again after worming him on the back of the neck?

Ivermectin kills scaley leg mites when taken internally. You will not see a difference until his scales start to grow out.

I would not dose him again for at least a month.

Thanks!
I think I may have already killed the mites via suffocation with an anti-fungal we were trying before the diagnosis was confirmed.
What I'm seeing may just be raw skin waiting for the scales to grow back.
