We bought a second buck for this reason, if we keep any doelings from one breeding, we can breed them to the other completely unrelated buck and at least have a good 2-4 years with only two. If anyone gets aggressive we will send them to freezer camp but until then, our boys are sweethearts with people and other animals. They are still babies but we worked hard to get them this loving and friendly so why would we sell them just because of limited gene pool?
it also prevents spending money feeding something that does not give back if you have 2 breeding bucks vs a buck and a wether.
Also bucks tend to abuse wethers... Having two bucks is a little more of an even match. My wether is twice the size of my buckling so I haven't had an issue yet. But I am adding a second buck next year and my wether will be moved to live with the ladies (lucky him!)
Would you recommend bringing on another adult buck or a young buck? I'm worried my buck now would fight? He's usually very friendly, but as of late, he's been quite the butt head.
Well he's in rut. He'll be more enjoyable when breeding season is over! It is always better to put like sized goats together but I don't think you should walk away from a good deal if you find a buckling either. You'll just have to keep an eye out and give the smaller one a place to get away if he's being picked on too much.
Many people have to separate the bucks during rut. I am not sure how to answer that... I got both of mine in the same year to grow up together to try to avoid fighting... Maybe a younger one that would be submissive would work better, maybe not. I do not know...
I agree with @NH homesteader about giving the younger buckling a place to get away. We have a older buck and kept 1 of his bucklings from this year- and the little guy does get picked on especially when any of the does are in heat. We have Nigerian Dwarfs so each month they come into heat.
Ummm Many folks do line breeding; father/daughter or mother/son to try and enhance wanted traits. Not something you'd want to do to enhance "bad" traits, so you'd typically only do it with good animals. There's nothing wrong with it but not something to be repeated down through generations. Many also breed 1/2 siblings and "cousins" for the same reasons. But again it's not recommended to be continued down through generations. Since you're just starting out, it will be several years before you'd "need" a new buck. Not trying to put a damper on goat math mind you... and I'm all in favor of adding "just one more"
Much also depends on what you'll be doing with the eventual kids. If they are strictly for the freezer, then inbreeding makes little to no difference really, until it gets to the point that you're producing non-viable kids... If you plan on selling them to someone who wishes to start a breeding program of their own, you should just make sure the potential buyers are aware that you've been doing line breeding so they make sure to bring in new blood lines and not further interbreed from the stock they buy from you (unless they know what they're doing).
Getting a wether to be a "buddy" for your rutting buck often means that the wether is going to get mounted/abused repeatedly during the rut. As long as you keep the buck within close sight range of the does but with strong fencing between them to keep mating from happening, he should be fine. Some bucks, maybe not, but many are. IMHO most issues with separated bucks happen when/because they're basically placed in "solitary confinement" where they can't see or talk to the other goats. Sectioning off a separate piece of pasture to keep him in sounds great. Hot wire will become your (and your fence's) best friend
