Mine hatched in about two weeks from the day I found the egg mass. Then the tadpoles were everywhere overnight and then it took about three weeks to see the toadlets begin to hop out on the dry areas...There are still a few tadpoles left in the pond, however, most of the toads have left for better eating grounds...In the flower beds around the pond...

Are they single eggs or eggs en-masse. If they are bullfrog eggs than you may very well expect to wait a month for the final eggs to hatch. The bulk of them sooner. The maturing time of the tadpoles depends on the species. Bullfrogs again taking the longest (up to two seasons). Often store bought bull tads are already a season old.

Yes they are bullfrog eggs. I think that I have been adding your basic generic bullfrog as well as leopard frogs.
