......the only way to tell for sure is to see the act or a breeding harness that leaves a color behind when bred (I have purple goats right now ) you can keep a eye out for her tail being messy she will have mucus on her girly parts and tail hair but some have that with just a heat alone. If you see it write it down as a due date to be on the safe side. And some seem to leave no sign behind when the deed is done.
Well I was going to say that too bit thought we were talking goats lol.....I know nothing of sheep so I don't know if the messy tail goes with sheep I would go for the harness if you really want to know when she is bred. The calk isn't that expensive and you can use the harness for years.A male sheep is a ram
