Hi everyone! I have a SF hen that has what looks like an adult version of past butt (poop on her feathers under her vent), bt she also has something coming out of her vent. I took a pic. I tried pulling on it a little bit, but there was enough resistance I stopped. Other than this, she is fine. Eats, drinks, hasn't layed in a couple of days, but that's not unusual. Can ano=yboby tell me what it is and what I can do for her? I've cut away most of the dried, stuck together, poopy feathers, but need to soak her rear. I just want to get some advice before I start. The yellowish stringy thing is what's stuck.
