I just noticed my KC female has a bunch of poo stuck to her bum and it looks inflamed. I tried to see if any of it would just come off but it was stuck on there and giving her some discomfort. My other two adult ducks and five 7-week-olds all look good. I just moved to a place with a quarter acre yard so they are roaming and eating whatever is out there including their usual grain. When we moved (5 weeks ago), the big ducks all went into a molt, probably stressed out from the move. The KC never molted her wing feathers and she never has in the past. She is 21 months old. So her wing feathers have looked raggedy for a while. Any ideas for treatment and for why this might be happening?
