Is my easter egger sick??

My rumpless easter egger is constantly having a dirty butt. Its not pasty and covering the vemt but its like constantly leaking. Idk if its diarrhea or just some kind of fluid. I have given it litttle dip baths to clean it but them it get dirty again. The other birds are starting to peck at it. I have seen it go tothe bathroom amd it looks normal. She does let out a peep when she goes. Idk if it hurts or not. Any ideas whats going on? Sorry about the graphoc pictures.
