I've got 3 5-day old piglets in the house. This morning they ate fine, but when I went to feed them this afternoon one of them wouldn't eat and could barely walk. I've given him a shot of penicillin (and will continue to do so as long as he's alive) and have been giving him electrolytes and water with a syringe, but he seems to have no use of his back legs at all, still won't eat, and is very lethargic. I have them under a heat lamp (he's separated from the other 2) but he is still shivering, his underside is bright pink, and looks to be wasting away. Is there anything more I can do for this poor baby? Any ideas what could be wrong with him? I've been searching the forums but can't seem to find anything that matches. Thanks edited to add: I went downstairs to give him some more electrolytes and he was gone. Thanks anyway. If you have any ideas what may have caused this please let me know. I will be taking the remaining 2 piglets into the vet tomorrow.
