Starting with our original pair of breeding Scalies where the female was visual - yellow or mustard, and the male a normal green. When we bought this pair we also obtained five green and two olive scalies that were all supposed to be their offspring. These were all quite young birds and at least two of them were under three months old. Two of the greens were males.
A visual yellow female with a normal green male will produce males that are
split and normal green females only.
The evidence we have supports this as the original pair never produced any
yellow/mustard/cinnamon visuals either male or female. All their offspring
were either green or olive. This raises the suspicion that the visual hen was
in fact a mustard and this is how olive (grey/green) chicks were produced.
(mustard being cinnamon and grey/green)
Of the known offspring two of the greens were males, these should both be
splits.
This pair, a split to cinnamon male and normal green female have produced four offspring in 2001, two are cinnamon and two are green. The two cinnamons are females (dns sex tested), one green is sold and the other could be a green male or female or a split male. (pending dna sex testing).
The simplified rules with sex-linked colour mutations used here are:The cinnamon colour variation with green birds such as these scalies results in plumage that is yellow and green, the green tends to overlay the yellow. Other parts that are usually black are instead brown to a lighter horn colouring. This includes beak, edging to flight feathers, feet skin colour and toenails.
