Okay.....been absent for a couple of hours doing "sick chick mommy" stuff.....I boiled eggs and mashed up the yolks (haven't given them any of that yet) ...... went to store and bought plain yogurt ..... had to go buy another feeder and waterer ...lol...... had an "AHA" moment while driving past 
PetSmart......Mealworms!!!   I figured if the EE wasn't going to eat anyway, what could it hurt to try?!?!  So, I mixed all three sets of babies some crumbles and yogurt (my oldest, last weeks babies, and the sick babies), and put two small mealworms in with the EE ......worked like a CHARM!!!!!!!!   It took a while for the baby to get interested, but eventually it couldn't resist all that wiggling!!!!  She ate both of them!!! She actually wandered around in the brooder for a few minutes, got a sip of water, and lay down WITH the banty babies!!!! (She's been on opposite side of brooder all day)  She looks more alert than I have seen her!!  I know there's still a long way to go, but I'll take what I can get!!!  (and I did put in some parakeet grit)
I also got some tiny cotton swabs and treated all the little bottoms again before I left for shopping, and I actually penetrated their vents just a tiny bit with the swabs ...... there were poops in the brooder when I got home!!!!!!!  BIG ONES!!!!!
I'm almost afraid of doing too much, but want to try every idea to find what is going to work!!!  Now, I have a little bit of hope. (but still cautious with my excitement)
Thank you all for your replies and ideas ...... and especially for your encouragement and concern!!!!  I will keep everyone posted.......
