My 9 month old chicken was walking very slow so I went to go check on her. Upon bringing her in I noticed that she had a prolapsed vent. I gave her a bath and cleaned her up when I also noticed that she was not only swollen down there but she was also oozing white. Whenever she popped the vent back out I saw that I was coming from right above the swollen vent. From what I can tell it is either an infection or vent gleet.
