Chicken Pox

If you don't get Chicken Pox from chickens, why does one of my chickens have it? For whatever reason they call Chicken Pox, Chicken Pox, there's nothing left to call what my chicken is suffering from than Foul Pox. 

I found her teetering in front of the waterer this morning. I picked her up and saw that her beak was caked and bloody with a warty-looking swelling on it, as well as her comb. I whisked her into the bathroom to clean what I thought were wounds and found that her feet and legs had scabs on them. And on the back of her head, I can barely describe. It looked like she had a small rock stuck in the middle of a tumor. I cleaned her up and tried to soften the lesions with warm water and vitamin E oil, but no result.

I called the hatchery and they had no idea what I was describing. I called the vet and they also didn't know, but said I could bring her in on Saturday. "I don't think she'll make it that long." They told me to refrigerate her if she dies and they can run tests and see if it's contagious and take precautions to protect the rest of the flock.

I got on (I LOVE) the internet and tried to Google for a clue. "chicken tumor," "chicken lesions," "chicken diseases," etc. until I found mention of the pox. Google images confirmed that my little chicken has Fowl Pox. There's nothing to be done about it once the chicken has it and in most cases they eventually get better. Unless the Pox has spread to their mouth and throat, making it difficult for them to breath and eat. My chicken is wheezing and won't swallow the yummy yummy special food I made for her, so she's most likely doomed.
