My doe has been in heat about a week so I've decided that I would like to breed her. I went onto Fias Co Farm and it says that Estrus/Heat Cycle is 17-23 days. Then it says that a heat is 6 hours to 3 days. Can someone please explain this to me? I'm confused! I already have a buck lined up and I don't want to loose the opportunity to breed her. Also, how long does she need to be with him to be successfully bred?
