The cost of a Fife Canary will vary considerably
depending on where you purchase from and in which city in Australia.|
The cock birds are usually more expensive because of the higher demand [the Cock bird is the singer].
If you want to get quality Fife Canaries you should be talking with a Breeder as most Pet Shop birds are the breeders rejected birds [scrubbers].
Consider joining a club, meet other breeders who will give you access to better quality birds for less money.
