How should I catch baby rabbits?

Question
As it turned out there are at least 3.  This evening I was able to catch 2 of them when they were feeding with the adults on the pile of grass.  I handled them but decided to let them loose because I didn't know if they are still nursing. Their mother would certainly be able to take care of them better than I.  Maybe they'll be easier to catch now they've been handled.  The other baby wouldn't let me get close.

Would the mother doe be drinking more water to produce milk?  Would I be able to see her groom them or are they too old now?  One of the kits had crud at the corner of its eyes as if it hadn't wash.

-----Question-----
Today I saw two baby rabbits.  They were running around and eating grass.  Their parents are former cage rabbits now free-range in my backyard.  

How can I catch the babies so I can handle them to become pet rabbits?  They probably never been inside a cage or had any pellets or treats.  Their parents allow themselves to be handled and it would be nice if the babies don't become wild rabbits.

How many weeks old are baby rabbits when they start running around and eating grass?  Will they eventually follow their mother to the pellets at feeding time?
-----Answer-----
Kits start to leave the nest between 15 and 21 days - depending on the weather and how much milk the Doe has.  They start eating solids at around 21 days.  Yes, eventually they will follow the Doe to the pellets.  If you sit very still and talk to them, they will eventually go to you - rabbits are very curious and as long as they do not perceive you as a threat they can be tamed.

Answer
Some does produce milk on very little water , others drink lots - I always have a liter of water in a lactating does cage.

Conjunctivitis is common in weanlings due to a dirty nest - catch him and put some eye drops in its eyes - any drops you use are ok.

The doe will groom them until they leave her.

Yes, a doe can certainly take better care of her kits than a human - they are so much fun to watch !!!
