One of my new chickens (~5 months old) was straining. Now she has a red bulge out her vent. It looks like it contains a partially hardened egg. I can see about a 1" portion of it and it feels pretty soft. What do I do?? She was pooping before the bulge came out -- that's why I noticed because it was running down her backside as she was straining. I put her in warm water and then the whole red bulge came out. Not sure what to do now!
