Onthespot ~ honestly, I'd take the trade, but sadly, I am in Idaho ~ I just don't have an extra space for them outside that would be safe.  I thought that they could co-exist with my larger hens, but  after reading UrbanChickenFamily's post, I am thinking that would be a poor choice on my part.  
Also, where do you get Ivermecin?  I think I will try that & some tea-tree oil & vaseline.  Hopefully that clears it up.  I wonder if silkies are just more susceptible to scaly leg mites?
KellyHM ~ in the pics, do oyu see how the scales on the chicken foot & leg seemed slightly raised?  as if there is a gap between them?  That is an indication of scaly leg mites.  I don't think this is a raging case of it, I have seen pics ont he internet that look 100 times worse, but it does look like mites to me.  I wondered if maybe the scales on silkies are just looser or something than larger standard hens ~ but everybody seems to agree ~ I've got a few mite-y silkies ~ lol.
UrbanChickenFamily~ Thank you for posting, I am definately not going to put the silkies in with the standards now.  I guess they will have to stay in the house, quarantined in the brooder till Wood Genius can make me a separate pen for them.  And I am sure you are right about the care part ~ Come to find out, these chickens came from a gal whose husband had died, he loved them, she hated them, so she pretty much ignored them until my friend picked them up from freecycle.  But at least the lady cared enough to put them up, she could have just let them languish completely, I suppose.  Not to mention she was likely a little grief-stricken due to her husband's death.  I guess " but for the grace of God, there go I", eh?
JennsPeeps ~ Thanks for the site!!  I am also a newby chicken owner, ( since about March-ish), but have found so much helpful info, both here & from many many books, magazines, websites, & nice people at the feed store.  
I'm a little nervous to give these gals a bath, as they don't know me too well ~ also, I wonder if they scratch me with their toenails, and they have scaly leg mites, can it transfer to a human, sort of the way scabies does?  I am trying to find out info on that right now ~ still unsure.
Tiki ~ thank you for the suggestion, I actually do have some BagBalm around, is that the same as udderBalm?  Perhaps that would be better than teatree oil.
Smartie_Pants ~ uh oh ~ roo-ish?  What signifies a roo for a silkie?  Neither of them look like they have big combs or anything, but maybe silkies don't have big combs, I don't have a clue there.  Also, if one was a roo, wouldn't he try to ride the hen?  Or crow?  But see, maybe silkies don't do what standards do,  again, I don't have a clue.  Or maybe they are just trying to get used to the new strange environment before they comfortable enough to ...~sling feathers..~? lol ~ Enlighten me, please!!
