Did I screw up my worm bin plans? Yes. Help!

So I made the worm bin and I put some organic produce scaps in there. And then the lid got left off for several hours (don't ask) and it got flies.
UGH.
Lots of flies.
So we put it in the sun to see if that would cook the flies.
Nope.

I don't think worms and flies mix.
So.

Added more dry compost--newspapers--and a load of chicken manure--to the bin--and backed off.

Options seem to be:
Throw the whole ugly mess out somehow
Pray it turns into compos FAST and then restart as work bin.
Start new worm bin, leave this as compost bin.


Any ideas
