I bought an Alpine doe about a month ago who had been kept with a buck for 3 weeks. They were not sure if she had been bred. Today her vulva was a little swollen and red and she had a very slight clear discharge. I took her to my 6 month old buck and he was pawing and sniffing and doing all the buck things at her, but she was head butting him and biting him. When I held her collar he sniffed her rear extensively and bit at it and acted very excited but didn't mount her. Of course he has never done this before, so I'm not sure if she is not in heat or if he doesn't know what to do. I have been watching her for tail flagging and other than right when we brought her home, and only when she was fed or petted, she hasn't done so. I don't want to find out next spring that she was never bred, but am having a hard time figuring out if she was!
