I NEED HELP WITH GOATS!! PLEASE HELP!!?

Hi, we are thinking of getting some goats and i need some help. OK we have a 10-15 acre field would they be ok or would we have to fence a bit off? We own a deer park and we have some stags would they be ok to go in with the deer? We are going to get a 18mnth sannen nanny with her little kid. If we got 5 bales of hay how long would they last between the two? Would an open shed be ok? its a dirt floor with feather edge board around the sides. Also we have chickens so the fox shall be attracted. Would the kid be safe with its mum if there is a visit by the fox? Also she shall be milked so can you tell us the essentials that shall be needed for milking and for the kid? Can you tell me other essentials that I will need??? THANK YOU!!!!!!!!!!!!!!?????????????
