6 wild baby bunnies

Question
I have 6 wild baby bunnies I've rescued - their mother was hit by a car-.  Their eye's aren't open yet, but they're eating about .7 ml of kitten milk twice daily.  I've done the rubbing a warm cloth on their backside (rectum) area and they're still not pooping.  They're very mobile around their cage and don't seem to be suffering, but I'm worried about the lack of bm's.  Any suggestions?

UPDATE:

Hi, just wanted to make an addition to the water comment.  Always make sure they have water.  Replenish the crock with fresh water at least once or twice a day.  Cuts down on hair and junk and they will drink a lot.  Also once they are off milk they need to always have hay and grass to eat.  This needs to be replaced often.  Don't give extra food pellets, they need (and are designed to eat) hay and grass.  Probably more hay than grass is better and safer.  Don't feed any fruits or veggies at this young age, and definitely no sugary items or high carb items.  They are designed to eat scrub and low-nutrient foods.  They run lean and mean, you will mess them up with too rich a diet.

END UPDATE

Hi,

you can feed them more often if they will take it.  Also, if you mix up the KMR with cream or heavy milk rather than water, that will be better - rabbit milk is extremely rich.  If you make it richer you may be able to feed them twice daily and they'll get the amount of fat they need.

Also I would get some Bene-bac (beneficial bacteria) from the local pet supply store and give them this daily - a little squirt or two into their serving of milk.

Keep doing what you're doing.  Make sure everyone's in the nestbox and sharing warmth.  Use soft, clean cut up cotton towels or tshirt pieces and keep them in there.  If you can hang a 60 watt bulb about 2 ft over them they will get a little indirect warmth.

Thanks for looking out for these little guys.  You may want to start scoping out any wildlife rehab groups in your area and see if they can take them.  Not saying they won't do okay with you, it's just they raise them so they can survive in the wild.  In most places they have laws about raising wild animals as pets.

I don't know how you're housing them now, but a large dog cage with a big front door could work well.  Gives them room, and you can make a second level shelf that rests on the horizontal cage bars to give them more surface area.  Big door makes it easy to get access to them and eventually change out the nestbox to a litterbox.  

Once the eyes open you can give grass (no pesticides on it) and dandelion leaves.  Small amounts at first, still keep giving milk for 2-3 weeks after eyes open.  As it gets closer to the end, start giving less and less milk, and increasing grass and dandelions.  You could give them timothy hay from the pet supply store, too.  You can also give timothy hay food pellets in small amounts.

Give water in heavy ceramic crocks.  This is how they drink in the wild.  

And on the cage floor, you should line it with soft cotton (expendable) towels.  When they need to be changed, replace with another set.

Again thanks for caring about these little ones.  They will love you forever for the kindness.
