Let me start by saying that I'm new to chickens so every experience is a first for me. A little over a year ago I rescued 9 chickens, They were all sick when I got them. Fowl pox/mites. The pox has long since gone away but now I've noticed that they have something that appears to look the same but 100x worse. The black scabs are much much larger and almost cover the entire face area on some of them. Also theres a lot of feather loss around the neck and face area. On my largest rooster I noticed that besides a few scabs on the comb there also appears to be a white almost waxy like substance on much of it as well. My google searching has led me to believe that it may be favor. Based on the photos does anyone have any thoughts? If it is what causes it and how do I treat it? Also is it contagious people? Other animals? Dogs? Pig? Lastly I'm on day 17 of incubation from eggs taken from these guys. Will the chicks be born with it? If so what do I do? The incubator is in my house and I had planned on keeping the brooder inside as well because it's still freezing occasionally at night. Am I running a risk of contaminating my house? Any info is helpful. Thanks!
