My Americauna hen has white spots on her comb that look like small bright white grains of rice. Acting fine, but want to confirm not parasitic or disease that may worsen. Other hen housed with her fine with no spots on comb, but lost a 3rd hen from that coop two months ago inexplicably.
It may be the beginning of favus - do an on site search - however I am not certain. I'd just keep an eye on things with her.
