Silkies, am I right!!
Hiding his nasty fully infested legs, under his full fluffy leg feathers..
I have never had to deal with this yet, but his legs look like cauliflower... Soooooo many chunky think flakey lifted scales, so big, I thought they were his leg feathers. My other silkies seem fine, but I dont think I should take chances.. Nothing red or irritated looking.. I quickly dusted his legs (with the last of the gardening dust with perithimine) before bedtime. I was researching on here, and saw someone used Ivermectin pour on for cattle.. I do have that on hand, as I used it a few weeks ago on my baby goats for their lice.
Application gor this on chickens wasnt totally clear from all the reasearch I looked at on this site..
?egg withdrawal? ?drops on neck?
?adding it to water and soaking a bird? ?treat repeatedly?
I have 24 birds to treat, I would like to treat all in the moring before I let the out of the coop. I have a scale that I can weigh them on before giving drops on back of neck.
My major infested silkie, I can also treat him more drastically with an oil and vaseline to releave any discomfort, but not realistic on 24 birds.
And we are in a hard winter right now, so soaking a bird with water and sprays, will cause more problems... But a coop clean out tommorow is possible since we may hit 45degrees

Can you post some photos?

Correct dosing information for Ivermectin Pour On is found here:

Ivermectin is not approved for use in Poultry so you would have to do some research/reading to find a withdrawal period that you are comfortable with.

Dusting can be helpful for mites/lice on the body and to treat housing as well. SLM can slowly migrate from bird to bird, so that would hopefully take care of them if they are not living on the bird and on roosting bars, nesting boxes, etc. Repeat housing treatment in 7-10 days with a Permethrin based poultry spray or dust.

SLM live mainly under the scales of the legs, so dusting and/or spraying unfortunately is not that effective on killing them on the bird. You are right to slather on some type of oil to help smother the SLM. Vaseline, Castor Oil, Nu Stock, etc. can all be used. Apply your oil/ointment of choice a couple of times a week, working it into and UP under the scales.
Hard to know how bad without a photo, but from your description - as time goes by the "cauliflower" (build up) will likely start coming loose so you can work that off too.

If you find you aren't comfortable using the Pour On with your hens or the timeline of egg withdrawal is too great, you may still want to consider treating the rooster unless you have plans to eat him in the near future.
 
I did look up the FDA "opinion" of ivermectin on poultry, they kindda walk around egg withdrawal as being so trace of an amount in eggs, that it's not significant enough for a cause of harm... So i found one of my barhams with the same sever condition today.. So coop cleaned out and everything dusted with permethrin dust... And dosing everyone at dusk once in coop for the night... Since hubby let them out this morning before I could even wake up 😆
