Keeping male rabbit with female

Question
Dear Sir
Thanks for all your advise and help.
I'll keep in mind all of them.
Can you please answer one more?
From when can i keep male rabbit with female because it's only one day since she has given birth?
Would she feed her babies, i am asking this because i have to spend my whole day in college and that is why i haven't noticed it. Once i am at home i haven't seen her feeding them.
And one of the babies' one ear has been cut off (perhaps it happened when she was cleaning them after giving birth). Will it reappear?
And can we touch them or the doe?  

Answer
the buck must be kept away from her for at least 6 weeks this is when the kits are weaned off her.
dont expect to see her feeding them she will do it when all is quite

the ear will not come back have a vet check it.
start picking them up at 10 days old
