Help! My hen’s butt smells really bad!

[Roosterfeather]

hi everyone my name is Roosterfeather! I just joined today and I have some questions. Sometimes my chickens get sick and I need help. I joined because my hen has a really stinky butt and it smelled like Dead! and I was wondering what was wrong with her. Now I’m starting to think it’s vent Gleet
