Last night we discovered one of my hens with a egg bound soft shell egg. We quickly and carefully removed all of it, but the egg smelled foul and rotten. Said hen appeared slightly less active later that night but not terrible. This morning before I went to school I checked on her and found her limp and unresponsive. She was in a dry cage of shavings but had a wet butt and underbelly with white-ish discharge. I could not tell if it was droppings or pus. I immediately scooped her up and ran her inside, cleaned off her bottom and set her in a dry towel. My next step is going to be a warm soapy bath where she can soak. But I am truly unsure how to treat her further. I have terramycin on hand if that is any help. She is still fairly unresponsive unless moved, and lays completely limp. She cannot stand on her own.
