I had a ewe that was getting no where and when I checked all I found were 4 feet. After some working(and praying) I got one of the twins out and the second took considerably longer because the head was turned back. It was the first time that I had to be this aggressive in a delivery(never in past my wrist!) I gave her a shot of 10cc penicillian, that was nearly 48 hours ago. She seems a little droopy(or am I imagining), but is eating and chewing her cud. I imagine that she is somewhat sore also. Was one shot enough as a preventative? What should I be looking for as a possible problem?
