Hello

i found a newborn baby rabbit laying on the grass on my front yard(next to drive way)

put a box (only two side up with top) around her. just keep her away from strong sunlight & heavy rain last night. is this bad idea? should i remove it?

Was it just laying there or was it showing signs of movement? I am wondering if an animal (cat, etc.) got ahold of it, in which case it may have internal injuries that are not apparent. If the baby rabbit isn't in its nest, the female will not feed it. The best option is to get it to a wildlife rehabilitator. You can find them in Cook Co. at: http://web.extension.illinois.edu/wildlife/professionals.cfm

i found her wed morning - squirmed. Now she's crawling.

in its nest, is that mean inside nest like rabbit hole? there is some kind digged-spot (slightly cover with dead leaves etc) rite next to her. i'm not sure it's a nest.

That's the nest. Check to see if there are other young still in the nest. If so, put the rabbit back in with the others. (The female will come back even if you've touched the young. Be sure to wash your hands w/ hot, soapy water after touching the rabbit). If there are not other young there, an animal likely found the nest and the female is not likely to return.

can't find hole entrance. all cover with dirts. should i dig it up to look for others?

she's out on the grass since wed morning. survived and crawling today. is this mean mother-rabbit is feeding her?

should i remove the box?

Remove the box. Typically there's dirt at the front of the nest from where the female excavated the hole. The nest is about the size of a woman's hand and only a few inches deep. It will be covered with grass or other cut vegetation and the liner will have grass and rabbit fur lining it. (If the dirt patch you found doesn't match that description, it probably isn't the nest). Stick your hand down into the vegetation covered part of the nest. It should feel warm if there are young still in the nest. Don't be surprised if they jump up a bit and make tiny squeaking noises. If you disturb the vegetation while looking for other young or putting the rabbit back in the nest, just reconstruct the nest material the best you can. If the female is going to come back, she'll "repair" the nest the way she wants it. They are tough little creatures and can survive a few days without being fed. But it will soon die of dehydration if it isn't being fed. If you can't find the nest w/ other live young in it, the rabbit really needs to get to a rehabber so that they can either care for it or humanely euthanize it.

found nest with three more babies in it. put her back in. placed two thin twigs in an x across the top of the nest to check if mother's came back to feed her babies. (http://www.messingerwoods.org/babybunny.htm)

check this morning, twigs r not removed. should i contact wildlife rehabilitator if twigs r not remove by tomorrow? or few more day?

i didn't wanna keep disturb their nest so didn't check on babies as 'linked site' said.

The female wouldn't remove the twigs. Have you checked the nest today?
