PLEASE HELP! TUMOR ON MY BABY DUCK??

[QuakieChan]

Please help! Recently, I was petting my duckling and just running my hand through her fur when I noticed a little bump where her stomach is. I was concerned because I have never felt it before and I'm genuinely concerned as to where she could have gotten it. I held her up to inspect what it could be, and you can see the little tumor in the pictures tagged. When I touch it, she doesn't seem like she's in pain but she does bite at it occasionally. I vent sexed her on the day she was born so she is for sure a female, so I do not believe that this growing appendage is a male genital. It's black and seems to me like a blood clot but I honestly have no idea. Please give me advice before I take action! I don't know what to do! Please help!!

Belly button.

No worries, it's just his belly button.

Like everyone else said, it's his belly button (umbilicus). Do *not* pick at it!

As mentioned it's the umbilical and you don't want to fool with that. It will scab and fall off on its own...
