I've not had a test done and when I last checked it was something like R100 for the kit/test/registration.

never really looked at the cost per test. I thought it was 1-10 test total price. Hence always trying to get 10 birds together for testing at once. My blonde is showing!
Since finding out I could have it done I have not ever needed to test for DNA. I have contacted them to find out now out of curiosity. Perhaps it's more expensive than I anticipated with the cost per test included.
At your quoted price it would not be viable. The cost of the test is more than the bird here, so I am ASSUMING it is less. Has to be or breeders would not bother.
