I have an 8 week old Polish/Silkie cross that has an issue with pasty butt. This just started this week. I have to clean her daily. She is the lowest in the pecking order and I never see her drink water. I don’t know what to do. I brought her in yesterday and cleaned her good, when I took her back to the run the other chickens attacked her, especially my little roo. He kept pecking her head. What can I do? My chickens have never had pasty butt. Also, my coop and run are big enough for 10 chickens and I only have 5. Thanks for your advice!!!
