foul pox

My chicken is about 8 months old. When she was 6 months she came down with foul pox, and it hit her hard. We finally have her at a point where she can be around the other chickens, but she lost a lot of weight and can’t gain any back. She waddles and falls over often when walking. Sneezes all...

Today i just noticed that under my rooster's comb there is a white scab? its huge and i have searched it up but not seen anything like this. and there is also black scabs on top of his comb which again i didn't paid attention to my chicken and now im finally noticing after searching up foul pox...

So, I was looking on here because several of my chickens and rooster have black spots on their cones that look like warts. I saw a thread that said they are called "foul pox" and are caused by mosquitoes. So these will go away on their own? How long does it usually take for them to go away...
