Hey I breed Boer xs , Boers & Myotonics(fainters). I dont breed before 1 year old. Sorry..but to me thats the magic age. And then only if that doe is a body score of 3.5 to 4. I cant say 80lbs..cause my myos some are minis They top out at 60 lbs. Lol My question are YOU ready? What catastrophes are you ready for? What building do you have for the worst kind of weather and worst case birthing? To be fair..the does depend on us to be ready to help her and keep the little ones alive. I watch my does and how they grow and intereact with.the buck Yes I put him in with a few does and aproned for a day or two. He will bring them in..and he gets them for a month. Some does & bucks dont do well. Ive had to pull a doe and put her with a different buck. I dont like any one hurt. My does go into a paddock with my buck for a month. He gets 5 at a time. For about 3 months. That way if any doe doesnt take the 1st month..she gets a 2nd try. By the end of 3 months..my boys are ready to be put back.into their own.place. the women have worn them out. They get thin and cranky..so the boys need to go get cleaned up and put eating first. Lol. And for me..I have groups delivering about 2 to 3 weeks apart. 5 does at a time. Thats how I am set up.
