UPDATE...
Pic of Dad and light coloured yellow with green back in the background showing white spot on back of head.
just some more pics of the young from this nest. its still interesting to see the colour difference in the 2 yellow young.
the very light yellow is starting to show a white breast ( which i thought could be an aus yellow ) but as it didn't have a mottled back i had my doubts, but thought maybe the euro yellow gene could be effecting it in someway.... maybe
but now i am thinking its just the simple fact that the white breast gene combined with the euro yellow makes the back lighter in colour. so 1 yellow euro hen has a white breast ( light in colour ) and the 2nd euro yellow hen has a purple breast ( darker yellow )
the only other thing that is throwing me out was the difference in mouth nodules of the 2 yellows, if they are both euro yellow hens then shouldn't their mouth nodules be exactly the same?? ( see pics in first post of mouth nodule difference )
my only other theory is the darker dirtier yellow back is a single factor male with a white breast making the back a yellow colour ( but his/her breast colour hasn't come thru yet )
at the moment most of the green back young seem to be showing purple feathers on the breast, no other white breast yet, still 2 more juvies that haven't shown any colour yet. if they are all purple breast then that will be interesting.
oh the fun of breeding mutation gouldians,
il have all the answers in a few weeks which should be good, iv enjoyed guessing the outcomes from this pairs babies. has really made me think
