Sometime overnight one of our bucks got in with the does, actually rammed the cattle panel hard enough to bend the bottom of it enough to squirm under.... I know at least one of the does was in heat yesterday, and there could be several more. I did not want to use this buck this year, however have wanted to keep him as he was our first buck, and actually greets everyone when they come in the driveway (is the friendliest buck to humans, not so much to other goats). I called the vet to see about giving all the girls a shot and he suggested esterumate????? Has anyone else ever used this and if so, how were the results? He suggested we needed to wait 5-7 days before giving all the does 1cc. Thanks!
