I have a buff Orpington that has a serious worm infestation. Until yesterday she looked great, was a bit more to herself but otherwise normal. I noticed a mess around her vent. When I picked her up to clean it up a bit there were actual wiggly worms dangling out of her. Last night she stayed in a nesting box but was on a roost that s morning. She wouldn't come out and her vent area was all wet and brown. I will go out and isolate her but I don't know what to do next. She's 3 years old. Any help would be appreciated. Also what steps should I take to disinfect the coop and run. Overwhelmed.
