Would an IRN breeder know what sex it is by IRN's parents?

[mickpmc]

Hi there!
I am about to buy a Ringneck and the breeder said he would
do a blood test and he would know their gender becuase of their parents ? Is that
true, would you know their sex because of their parents
Thanks

Hi Michael

I've never heard that one before... but I'm certainly not an expert!

Hi Michael

I have heard that it is possible, but only for certain colours. So it depends on what colour baby they are talking about, and the colours of the parents.
