About 5 days ago I thought I had an egg bound hen. She was contracting though no egg nor poop for at least a day. Gave calcium, warm baths, olive oiled the vent, etc. When nothing for 2 days, I did a cloaca exam and felt nothing. She just stands around, eats barely anything (tiny bit of yogurt and mealworms). She drinks water well. Then she started laying soft eggs that would stick to her butt and have watery poops. (no blood) I have one other hen, and 2 laying pullets, and though they all acting totally normal, they are starting to lay soft eggs too! I am waiting for a bag of medicated feed to come into my local feed store which should be today. I have apple cider vinegar w Mother and probiotic water in various watering containers. What else should i do? What could be causing this?
