My last hatch I had one a bantam cochin that I tought was not going to make it. She couldnt stand just flopped around on her belly. She did this for almost 3 days. I finally told my DH to cull her if she had made it through the night and wasnt any better. The next morning she was up running jumping acting fine. She still is. The only thing I did was the last night I started rubbing water with electrolytes and vitamins on her beak. Maybe that helped, maybe she just needed time, But I named her Miracle.
