Help with my pregnant rabbit!!!!!!!!!!!!!!!!!?

my doe rabbit may be pregnant. i dont know how she would have got to the male. but i had experiecened people tell me she is, i was thinkin the other day how cool it would be to have baby bunnies. we checked her and shes due sometime around august 5th. well, i started thinkin on either august 14 or 15th im going to the state fair for a couple of days. my pawpaw and mawmaw will be here with her and her babies. but i just dont feel right, i feel like i need to be here and i dont want something to go wrong and besides she my responsiblity. my mawmaw and pawpaw both use to own rabbits and they had 87 because they thought they had all males but they didnt. and they kept on breeding. but by the time i leave for the fair they should be 9-10 days old. i was wondering when do they start walkin or crawlin? and is it okay that i leave for a few days? and during those days what should be done? what do you have to do to them or after that do you just feed the doe? also will they be tamed when i get back if they dont touch them starting at day 9 and i leave for about a week? please help!!!!
