Lice, mites, dry skin, dark comb

[lylashappynana]

Hopefully these pictures will help someone help me figure out what is going on with this hen and what to do about it.

She's about 5 yrs. old
Layena layer pellets (not the Omega type which as I'm reading maybe would be a good idea?)

Her comb and face are dark. I'm adding a picture of her sister for comparison.

She had a sneeze/cough - treated with oregano oil and garlic and added ACV to water. Seems to have knocked it out.

Eating fine and very active. I don't think she's laying at all. Her face looks very dry and there's always little flakes on her back.

I've looked at many pictures and can't figure out where to start

Have you picked her up and looked for lice/mites?

Comb looks a little dry, you can put some vaseline on to help moisturize it. Comb and face have a slight mulberry coloring which looks normal to me.

I'm going to attempt to check her again today. When I checked her the other day the skin on her head is "scaly" and maybe there are nits? at the base of feather shaft but I don't see any movement of lice. Under her wings looks beautiful! Always has flecks of "dry skin?" on her black back.... at least I think it's skin.
I rubbed coconut oil on all the girls combs the other day cuz my barred rocks combs were also very dry.

Soooo if they are face lice do you actually apply whatever you apply to the face? If I apply Vaseline to the face will it smother them?

If there's lice, then you will want to use a Permethrin based poultry spray or dust. Treat all your birds and their housing.
