My miniatures also exhibit signs of heat around 8 weeks.
Whether or not it is an actual heat and they could get
bred, I don't know. I mentioned this to a friend of mine
and she was shocked. Said none of hers had ever done
that at that age. In the five years I have kidded out does,
every year the my doelings have started at around 8 weeks.
Whether or not it has anything to do with it or not, my
bucks are penned less than 100 feet away.
