for people who love the littlest dairy goats
My needs in Alabama are way different than what yours would be up north. Some of the others further north will be able to help you better but a few things about your herd will help, like... How many do you have? Do you have to house bucks, also? Do you plan on having herd growth or are you going to keep them at the present number? How much and what type of land do you have available? Do you have a barn presently or any convertible out-buildings etc.?
My best advise is to make something that works for you and is easy for you to manage. Unless you are under a restriction from the town you live in don't think that you'll stop at two goats. Therefore you need to think ahead and plan for extra space.
My best advice is to try to allow flexibility as far as pens go inside the barn. You never know when you may need to segregate a goat or when you may decide to bring a new one home :-) We have a segregation pen where new goats can see the herd but are removed from them until a week or two. If you need to segregate one due to injury or illness, it helps to have this available, because you will be under enough stress tending to the goat.
I already have one barn, I am in a town that is very restrictive about livestock. I am planning on adding anouther barn soon for a JR. pen and some stalls for kidding ect. my herd is already up to 6 does and am not planning on adding bucks, our farm is still in the making it work best for us stage, we just moved the animals homw after boarding for 6 years and going through a very tough permit process
