I moved a waterer two days ago that has been there for a long time. Underneath there was all funky stuff growing looked like plants ect. one of my BR ran over and started picking at it.I kept chasing her away but she kept trying to eat it. Anyway afterwards she was walking like she did not feel good and had runny stool not bloody. Now today she is weak stumbling has a dark beefy red comb and is in respiratory distress. I have confined her to comfort her. Could this be posioning? What could I do for her Please.
