If I have no idea when our does are in heat, and I want kid goats in very early March, then when do I put them with the bucks. A March 10th 2010 delivery minus 150 days would put breeding about Oct 12th. When do you put the doe with the buck??? 3 wks on each side of the 12th? I don't want them too much earlier, as it could be cold here in Michigan. Please advise. I can't seem to ever see when either doe is in heat.
