What does a goat being in heat look like? I know like flagging tail, swollen vulva, interest in buck, but how can you tell if you don't have a buck? Are certain goats just harder to tell than others? I have been trying to tell for years now what a doe in heat looks like and only when they are around a buck I ve been able to tell. Well this year my doe seemed to be in heat because she seemed to be super interested in the buck, looked swollen, and was flagging her tail some. Well today only like six days later, he seems to be really Interested in her and she seems to be acceptive of his attention, however if she is in heat today she couldn't have been last week, so now I m just kind of confused. What do you guys say?
