Good luck with your hen!this gives me hope. 24 hours since I found it right after she laid a perfect egg. these photos are from this morning. I have read to take food away...did you do this? She has water with nutradrench. I did put a small amount of oyster shell with her layer feed. She is in a dark place.
I'm glad she is doing better. Definitely keep feeding and watering her. Be sure and provide fresh clean water along with the nutridrench. Also provide her with a side dish of calcium.
Keep us updated. It is always (as you're discovering) uplifting to find threads with positive outcomes!
