My 1 1/2 year old buff orpington hen has had a messy bottom for the last three weeks. When we first noticed it we took a closer look and discovered what I believe to be chicken lice nesting around her vent (small and white). We sprinkled her, the rest of the flock, and the coop with seven dust. We followed up with treatment a week later. A few days later I noticed she had dried egg around her rear. I took her inside and soaked her in a warm bath, cleaned up the yolk, dried poo, and dried her. She looedk nice and clean for the first time in weeks. However, once again she is showing signs of a messy bottom. Her vent does not look irritated, there is nothing oozing, just dried poop and ruffled feathers. She isn't acting lethargic. Do I need to be worried? Should I continue bathing her as needed, or leave her alone and see how it goes? The broken egg concerned me, because I know it can be a sign of egg bound, but she hasn't shown other indications of that. It has been approx. a week since she last laid an egg, but she has been inconsistent in her laying since winter started. Thanks for the advice!
