Firebelly Toad Feeding Question

I have two firebellys, a green male and a brown female. The green on is an excellent cricket hunter, he rarely misses when he goes after one. The brown on is a terrible hunter, nearly every time I watch she misses the cricket and Greenie ends up eating the majority of them. My question is do you think something is wrong with Brownie or is this normal? I try to drop the crickets so they all fall right around Brownie so that she gets at least one.
