As I tried to explain, the photos of the 2 yellow birds are not related to the chicks/hatchlings. Just cant wait to see the results of the light babies but what the hell will be the result of the "dilute euro yellow cock" and "aussie yellow hen'. What really spun me out was I thought they were both cocks because of their beak colour.

Look at the "what are we" thread. It will give you some idea.

you also have to look at the hens belly, its a very light yellow and the quality of colour in the head colour is not as bright as what a male would have, to my knowledge no yellow mutation gouldians will have black beaks when in breeding condition. so you have to look at other signs for sexing, colour, tails spires, singing etc.

we also have to try getting out of the habit of saying dilute when referring to euro yellow mutation.

I didn't know this because all of my yellow birds have obviously been cocks and this would appear to be my first "yellow" hen. Don't really care if its a cock or hen but I have no idea how to differentiate between "euro" or "aussie". Original stock (males) had no "euro" in them( according to the breeder) but the hens I put them to were bought from a pet shop. 1st season produced "Aussie" yellow with white breast and white breast normal back cock. Then got given a yellow head dilute cock and yellow head hen which I thought would help in not having the flock inbreeding. Now I have no idea whats happening. Now I have yellow head cocks and hens, black head hens, red head cocks and hens (normals but more than likely split for whatever)), dilute euro yellows not to mention yellows with white,purple breasts and yellow heads. Funny though no black head cocks. Its all too much for me.

Misso, your going to have to accept the fact that 'Dilute' is still used for single factor pastel green by some people.

Matcho just wants to know what could his babies turn out to be.
@Matcho, sounds like you have some working out to do

This gets very confusing when we use terms like "dilute" for single factor yellow-back cocks especially when there is a recessive dilute mutation which looks extremely similar to a SFYB & which has a different mode of inheritence to yellow-backed. No wonder so many people struggle to grasp the concepts of genetics & modes of inheritence. Using identical terms to describe totally different mutations only adds to this confusion. Probably shouldn't say this but...I just cringe when I see a mixed colony of various mutations which the owner doesn't know what they possess. This cocktail of genes mixes randomly at each uncontrolled mating to produce a totally stirred up concoction of mutant genes in almost every clutch of young. These birds can't possibly be passed on to others with any certainty of genotype & so the frustrating cycle of confusion multiplies.

Totally agree Tiaris,i pm a mate last night and said this is the reason i got out of gouldians as there a cocktail of who knows. This is also the reason i specialise in two species now and hope to keep them pure.
