6 week old kittens dying! i dont know why?!?

ok before anybody gripes its late at night so i cant get ahold of any vets or animal control im just hoping someones on and can help for now! i live in a small town and i have no vehical to take them to the emergency vet (its 20 mins away by car)! i love my animals! i was gone all day (all my cats were fine) and i feed and watered them and put them in the bathroom so my puppy wouldnt bother them (there was nothing they could get into i already thought of tht and checked the whole room)! but i came home and one was dead and another dying(now dead) and 2 more seem weak and one of them are sorta stumbling! i gave them a hand bath (2 try to wipe anything from their fur but they are in a very warm place so they are safe there) and made them drink a little milk and water to get something in their stomaches (the other 2 are eating fine) but im scared im a real animal lover but i dont know what to do to try to help them tonight until i can find help! im gonna make them eat broth in 20 more mins but i need to know if there is anything else i can do to help until i can find a shelter to take them! btw the animal control wont give them medical attention some im trying not to do tht! :'( pleasee help!
