Toulouse with pasty butt

[Homesteadmomma3]

I have 2 Toulouse geese that live and coop with our 8 ducks. This morning I noticed that one of our geese Meredith was pulling at her butt feathers and it appears as tho she has pasty butt. My husband and I plan on bringing her inside to clean her up and take a closer look look at her vent area once he gets home (I can’t catch her in my own) but I don’t know really what I’m looking for, or how to treat her. What could be causing this? All our birds free range on our 3acres along with our neighbor’s property as well(don’t worry they love the birds) and have 2 ponds they spend their days in. She isn’t lethargic she’s eating fine and isn’t separating herself from the flock. How should I proceed? Thanks in advance for your help

You need to get a closer look to make sure it isn't a prolapse.
