So these are two of my chickens, Sophia and Blanche, they’re two years old and do not free range. This is the first experience of disease for me, and then. On 12/19/22 I started applying Vaseline and ordered ivermectin. I applied the ivermectin 12/27/22. Then someone said the faces are a fungus not mites. Ugh! Help!
It can be hard to tell favus crust from mite gunk (those are the technical terms ), but based on the improvement with ivermectin I'd say you definitely have a mite problem! As long as they are improving I'd keep treating with ivermectin every two weeks until the skin is healed. Also be sure to treat the coop and check your other birds thoroughly. You don't want the mites moving from one bird to another or some birds harboring a minor infestation to reinfect your silkies after you've healed them.
