One of my buns is sick I think she has the scours. Her rear is matted and there is some white looking material in the cage. The same white gunk is on her rear. I noticed this last night and put some terramycin in her water and used a syringe to give her some water. I also gave her some applesauce. Tonight she seemed to take the applesauce better. Any ideas what she might have? and how to cure it. She is due to have kits Sunday.
