Funny title, I know, but let me elaborate here. For a couple of days my hen has had a bit of a runny butt. She seems to poop normally, but her vent area has had some poop and had a bit of a suspicious crusty, discharge on it. We wiped her butt, so she's alright for now, but she's a bit on the lethargic side. She'll peck around with her flock and will spazz when we try to pick her up, which is normal, but sometimes she has to stop and stand and puff up for a while, which isn't normal for her. She's about six or seven, so she's older and that could just be a part of this, but what does this all mean? How can I treat this? No one else seems ill, other than occasional sneezing, but it seems to be dust-related... Could this be worms?
