Before you decide on anything, get a basic understanding of goat husbandry. The question of why do you trim hooves shows that you need to learn a great deal about the fundamentals of goat care.
Visit as many goat operations as you can. Talk to the most successful breeders about their farms. Look for advice from those with healthy, robust animals and tidy conditions. Read everything on the internet and library you can. Take your time and prepare.
Meat goats, to me, are much easier to raise as they do not require daily milking. A dairy goat prduces more milk than her kids can consume (if she is a good dairy goat which is what you should be raising), therefore she would need to be milked for months and months after she kids. It cannot be skipped and is not "easy". If you have several or quite a few milkers, it is quite an undertaking for a beginner. You should be knowledgeable in all aspects of breeding, delivery, lactaion, milk handling, diet, disease prevention....along with simple routine things like hoof trimming. castration is a MUST for half of the kids your goats will produce as they will be male and it only takes 1 good male out of many, many males born to carry on the species. There are a host of reasons why they should be castrated which I won't go into here. . If you are squeamish, you need to buckle down and get over it, or find an assistant who can do the things that you are not able to do. (Many are not able to dd thier own castrations at first).
I hope this post didn't come across wrong, I just want you to get off on a good start. Goats are wonderful and lovely animals and I only want your future goats to have a terrific life.
