Chicken butt mystery

[mommaford09]

Alright so my OG (older girls) I have had for 2 years now. About 3 months ago, I lost my favorite hen to some kind of dirty butt thing. Now one of my leghorns is having the same thing. She has diarrhea, very tired, not really eating or drinking. Any ideas about what could be wrong?

Has she been wormed?

I gave her an all natural wormer but also have wazine I was thinking of giving them. The all natural was a month ago.
