Fortunately I've never had to deal with lice, just mites so far, so I'm probably not the best person to advise you about them. But the picture with the white hen looks like the clumps of eggs on the shaft you generally see with lice, not sure about the darker hen.

It's much easier to spray them at night when they are on the roost. Get the permethrin liquid concentrate. Also you need to clean out and spray the coop thoroughly.
