Do not "close" this interesting case. Some thoughts: edge mutation keeps melanin at the outer parts of the feathers and show a decrease in melanin inside the feathers producing the edged pattern, typically in the wing feathers .... why it is just the opposite in melanin distribution in the nails? In your friends pics we can see that the tip of the nails are ligther than the basal parts. Is nails growth different than feathers growth?
We know that in feathers the first parts to be produced are the distal and outer parts. Is it similar in birds nails? Has anybody looked at the nails colour of edged babies trying to understand how melanin is deposited? Are they initially black and thereafter they lighten while growing or are they initially white and they darken while growing?
And this does not answer the case of the completelly albinistic nails of your bird. Could your bird carry another mutation, even recessive, able to decrease melanin? A mutation classed as recessive could become apparent in the split bird if there are other mutations already decreasing melanin content. I own a young green male double split clearhead fallow and cinnamon (father green Clearhead and mother green Cinnamon split Blue) which is lighther than any other of my green youngs making me think that neither Clearhead Fallow nor Cinnamon are true recessive mutations but rather incomplete dominant, as most of the mutations.
In fact i am not happy with the pics taken in the dark with flash, i'll update with daylight pics to compare apples with apples.
To me these birds are not dom edged. will get more pics.
Madas, Correct.
Recio misunderstood my blurred statement, thinking i am saying dom edge, also my pics were in edge folder. I acctually thought last night that the hen bird is cinnamon.
I did not say it as i wanted to provoc feedback.
Pictures were taken with flash closeup in poor lighting & under the neon lighting, it looked like cinnamon, i don't think pic is true to the birds color hence i will get some pics in daylight.
Could we see some pics of that female with a focus on feet, wing and tail feathers?
I have a problem with Cinnamon nails since they have been described ligth as well as dark. Is there really a specific nails colour in Cinnamon mutation?
You said : "If it wasn't for the nails, i wouldn't have paid much attention to her, as we expect to get slight variations in color]" ... but a Cinnamon hen is readily visible !!!
Parents: Violetblue hen X "Green" male
Breeder no longer has the green male so i have not seen the bird but i have seen the violet hen (mother) nothing unusual there: nails, feathers, as it should be.
So it is all to do with the male, if he was split for anything (he was not split blue) as all 5 young were green based birds.
So, going through elimination proccess the most obvious mutation is cinnamon, not many other mutations to consider.
Cinnamon, lighter then green, light nails (most times) lots of yellow.
I first thought of dom edged, given the bone color of the nails, but it was obvious from the first pics posted that it was not it.
Nails match, nothing else.
You might think... Where on earth do you get these birds?
Well, i travelled over 50km to pick this up, for that single reason the nails in the pics shown attracted my attention.
