Yellow to yellow Gouldian question

[Grove]

Hi, is it ok to breed Orange/yellow head white breasted yellows(Gouldians) to each other or is it better to use normals ?
Thanks

Yes if they are Euro yellows but Aussie yellows and blues still need to bred from a colour to a split or out crossed to normals.
It is still a good idea to out cross Euro yellows every now and again to keep size and vigour up.
Euro yellow to Euro yellow will also give you Double factor cock birds as well. Craig
