I need help with yucky butt!

[Sierradavette]

I got this girl (along with my other first-time chickens) around a month ago. Off and on I’ve noticed her have a really dirty behind, but I always say I’ll give it a couple days because she’s acting completely fine. She’s a buff Orpington, around 1 year old, as far as I know she is laying. I have 5 hens and get 2-4 eggs a day, and one of those eggs is definitely from my smaller Ayam mix, so I’m almost certain she’s laying. Behavior is completely normal, eating and drinking happily.

Is this vent gleet or something else, in your opinion? Thank you!

Looks like poop. Mine get poopy butt. I clean it off with water and leave bird in sun to dry.

If it's very cold where you are, I would dry her off with a hair dryer before putting her back outside. You might trim some of that butt fluff, being very careful not to cut her.
