We had a 600 pound heifer calf that got into our huge fiberglass stock tank in the pasture. We think she was in there at least 24 hours before we discovered her, she was still alive and standing on her front legs but her back legs were sprawled out like a frog behind her. The tank is not really high on the sides but has a lip on the top that curves in and apparently she just kept slipping and could not get out. We got her out but she was down, her back legs were very stiff, we had the vet out, he gave her electrolytes, antibiotics, we got her home and treated her but she never ate or drank (we had to tube her water) and she never could get up, but she did try a little but not much. She died after 3 days like this. Anyone ever have this happen?? She was very alert in the tank when we got to her, she just could not get up.
