Doe kidded Sunday with big triplets, she got one placenta out Sunday and then the other took a while coming yesterday. This morning she has a little bit of placenta sticking about an inch out of her. I gave oxytocin 3 times over the course of yesterday and Sunday to help her expel the other ones. She is on penicillin because the kidding was difficult. Any advice? Should I give more oxytocin and/or lute? Call a vet? Any ideas are welcome. Thanks in advance.
