When mine are egg bound and still able to poop I have found that tubing 60 ml of water really helps. I tube 60 ml, wait 60-90 mintues and do it again if the crop has cleared or mostly clearded.
I also think that calcium gluconate works better than calcium carbonate. One can get the calcium gluconate at the feed store in the cattle section.
Edited to add:
Okay, so I just re-read the whole thread and I didn't read that you gave any calcium except for what you put in drinking water?
Yellow poop can be an indication of liver problems, bacterial infection, or dehydration. Can you post a picture of the yellow poop?
If you have been putting calcium in her drinking water I seriously doubt that she's getting enough calcium to do any good. Additionally, I've read that calcium carbonate is not as easily absorbed as the calcium citrate that
@azygous suggested. May I suggest that you go get calcium citrate from a pharmacy or calcium gluconate from a feed store then give the pill orally, or give the injectable by injection or orally?
