I have a 16 year old male domestic goose

[samboni95]

My gander has a pretty embarrassing issue going on with his private parts. They seem to be hanging out and he just acts like doesn't feel well. I'm attaching a picture as well. He also holds his wing down sometimes. Any thoughts on what I can do?

A prolapsed penis is a serious condition, as it may get infected. It's more common in ducks - try searching the duck forum for penis prolapse.
