Sick Chickens - Eggs Edible?

[chickenlady2017]

My chickens all seem to have very little - if any - feathers under their wings near their rears. Worried it's some sort of parasite or ... who knows. Just wondering if an infestation of any sort would mean their eggs are bad. They still seem to be laying alright but I'm worried I shouldn't be eating the eggs (?)

Can you post a few pictures of this area?

Have you checked them for lice and or mites yet?
I don't think there is anything to worry about when it comes to eating eggs from a chicken that has lice and or mites unless you are treating with certain medicines for either of those.
