I have a 1 year and 3 month old Appenzeller Spitzhauben hen. I noticed she has been a little lethargic lately, and resting more during the day. I picked her up because she appeared to have an issue walking and found this huge cancerous looking lesion. It looks like squamous celll carcinoma to me. It looks extremely painful and I thinking I need to put her to sleep soon as this I believe is only going to get worse. I have been trying to find pictures of anything that looks like but I havent been able to. So any kind of help would be hugely appreciated. I mean if its treatable, she's my favorite gal and I would hate to lose her over something I can fix, I just don't see this being fixable. She only weighs about 4 lbs as it is. The lesion is located on her right side just inside of her leg.
