Yesterday, I was checking all my chickens for head lice, (recently I had an war with a head lice infestation) Well, no one but this hen had some, I went straight to dusting her, and noticed a lump on her back, I was poking it and trying to figure out what it was, it moves freely, not attached to anything, but is hard, and white. At first I thought it was a bee sting, (there is a big hornet nest 3 trees away from the coop) So I thought, I could just treat it with some anti infection cream, and just take the needle out. Well, I took her into the bathroom to clean it, get the needle out, etc. I looked at it closer, and noticed it was bigger then a bee sting, and wasn't pink. I was puzzled about it because I didn't know chickens could get tumors, so I thought maybe something got her, and she got a puss bubble, or something. So I looked up what it looked like in Google, and it came up with all these pictures of chickens with tumors! So, I'm guessing its a tumor, am I right? Well, I don't want to go to a vet, and spend 100 or more dollars on a chicken, but, I also don't want to make her suffer, can I cut it out myself? Its free swimming like I said, and there is only one, I felt her hole body, and squished in some spots to check closer to her liver, stomach, etc, and none. So luckly this is the only one. I was thinking, I could cut a little line above the tumor, and lightly pull it out, then sow the line up with thread, and put some cast on it, and keep her inside for a bit. Also, sorry, but, no camera, so no pictures. The red blob is just where the tumor is. She is an 2 1/2 year old Buff Orpington, if it helps.
