The red is the naturally red featherless zone around my young Orpington Roos eye, the colour is enhanced with a filter on my phone.
I'm not positive how to treat lice on the face... I would provide a dust bath, the chicken will cover its self effectively I think.
Here's the roo without a filter...
I don't think its normal. Won't hurt them to be treated for lice.... But I'm sure someone here will know for sure what it is. You could try re-posting with your picture under a title like "is this lice". Could also be mights or other skin parasite....
