Which ever breed you need to call them theirs good news they are both chickens! Good layers even most of the time all the way through winter.
Enjoy what you have.
Ain't nothing wrong with australorp's one of our best hens from the free range flock (mixed flock of a buncha breeds) is a lorp and she is number #1 in the pecking order.
If you are not happy with them your best bets to find a reputable breeder focused on a few choosing breeds.
