I am going to use CIDRs this season to have kids Dec/Jan for our fair in July. I have gotten the CIDRs and have read and watched tons of informational stuff, I keep getting different things, how long to leave them in, use of Lute and PG 600, use of just one over the other, some says PG 600 works the same as Lute, some say use both. Can anyone clear this up for me? Give me some advice from those who use them and have had success. I am breeding two first time fresheners and 6 does, those who have kidded before. All Boer goats. Thanks!
