We have a very lethargic chicken that has not laid an egg today. She's hardly walking and looks like she is trying to pass an egg. She is not doing "the penguin walk" but does seem to be straining to push something out. We are going to give her a warm soaking and put her in a dark room over night, what else can we do? Update: My husband just stuck his finger in her vent. A good amount of liquidy white diarrhea came out, but he felt no egg. Thoughts? Update #2: She passed a soft shell egg this morning, and is acting normal again.
