I have about a year old zombie hen that I noticed discharge from her lower tail feathers. After looking further I could see her vent was swollen and hard. I soaked her in warm water with dawn soap. I can feel pieces of broken egg in her vent and was able to remove a few pieces after her bath. She has had a few bowl movements since then and is eating and drinking water. There is still broken egg in her vent and discharge. What are next steps? With it being Sunday I have availability to a vet.
