I know this may sound stupid but are you touching the eggs? I know you're probably not so the next thing is maybe get it a new nest. Find some raw hay or whatever and don't use your hands. Gloves would leave a scent too so maybe use a couple of twigs like chop sticks.
Also, half way through writing this, a thought came to my mind. Does your budgie have a mate? If not, it's just throwing out the eggs because no male has come along and mated with her to fertilize the eggs. Also, if you do have a male, make sure it's a male. Could be 2 females laying duds.
