You are getting lots of good advice. Many of us started out just as you are, with lots of questions, and not much experience. It is SO much fun! Re the guineas: I have 56 of them and they make a lot of racket, which we love,and they DO announce visitors, dogs, etc.. but they never "attack" like geese will. Geese are better watch dogs, but remember this: no matter what the fowl is, they all roost quietly at night and let any predator have its way with the flock. I loved letting the chickens free range but lost 2 to a fox, in one day, so now I use 1Premier's nylon/electric poultry fencing around an acre and so far haven't had any heartbreaks. My last comment: A farm is not complete until at least one roo announces the sun's rise and fall. Enjoy and keep posting.
