One of my hens who is around 7 years old has been lethargic, not hanging around the other hens, not eating or drinking from what I can see. I found her today away from the rest of the flock standing practically straight up. I felt her abdomen and I feel something hard on her left side towards her vent but not on the right. Could this be a trapped egg? Last week we found a larger normal egg in one of the nesting boxes but didn't know who laid it. Any help would be great. I did soak her 8n warm water but got nothing.
