have several chickens with white stuff on face where it used to be red

[tinahoak]

I have a several chickens that have developed a white "scale" ? on their faces, does not appear coming from their ears . At first I thought ammonia poisoning ? but the coop is cleaned out and then it developed days later. A few have puffy features . My coop does get sparrows flying in ( the darn things!) as I have the front door open ( yard is fenced) I have given them lots of vitamin A via fresh winter squash. it is just on the face , no coughing or sneezing or ill appearing in any other way. ( legs look fine, no scale) Coop has good ventilation................I am at a loss on how to help them get rid of this . I have not yet medicated their water . But I am going to do this today .
Any thoughts?

Thanks

I had something that looked like that too. Turned out it was new feathers coming in.... the new shafts are white. Could it be possible that they are molting?

thanks , but no. This is not moult related. As a few birds have puffy eyes and it is on the face where they don't have feathers............wish it was from moulting

What would you medicate with?

I tried researching but there is a lot to read through if you google poultry diseases. One possibility is head lice: http://msucares.com/poultry/diseases/disparas.htm#lice
Treatment is permethrin (Adams flea and tick spray, I believe)
