I noticed she was dragging her tail and looked lethargic (of course, they are all lethargic because of the heat here in S. Oklahoma). So we chased her down and I took a look. Her vent was clear, but just in front of the vent it appears irritated and a few scabs. There was a lot of poop in her feathers, so I cleaned her up with warm water and Dawn. She was very calm and closed her eyes like she was enjoying it. I put a bit of vaseline on the area and I've put her in a small pen beside the others with food and water. She will love the grass in the pen. Is there anything else I should do? I will continue to check and clean her up.
