I have also got NSL, this bird is wild taken cock. When it was paired
to Lutino hen all the chicks were green. The difference between the
two type is that the neck ring of NSL is brick red instead of
I also have a true fallow cock bird from the wild, the bird looks
exactly like a clearhed, without a yellow head. The eyes are Plum and
the body is same as Clearhead(Buttercup).
I have a few thoughts on your earlier posting, but am far too busy
with work at present to reply to them. I will post them as soon as time
As promised, I have come back to this posting to discuss the results

or another source. The only way to explain the 'dilute' cocks if they are
recessive, is if the hens were split as well as the cocks. Or else they
would have to be alleles of the SL ino.

the identification of NSL ino birds. Unless offspring are test mated, we
cannot assume they are NSL ino and not SL ino.
Also to go back to the first pairings, the 'dilute' allele could not
be allelic for a NSL locus because one parent was supposed to be NSL ino,
therefore would have two genes for NSL ino and no room for another allele
(dilute). If 'dilute' was allelic for NSL ino, it could not be carried by
the NSL ino birds. Therefore the possibilities for the 'dilute' are.
1) It is a mutant of a different locus - carried hidden by the ino
phenotypes - could be either parent in the original pairings, not just the
2) The original NSL ino phenotype was actually a combination colour
between 'dilute' and a second mutant which has not be discovered in the
mix - seems least likely
3) The 'dilute' mutant arose spontaneously and has nothing to do with
the original strange results.
Suggestions for matings to establish what is happening
Need to establish a true breeding NSL ino line, free of SL ino and
Test mate 'dilute' and 'buttercup' as you suggest.
Test mate both with NSL ino, but must have pure NSL ino first.
Results above suggest all NSL ino birds would be carrying both SL ino and
I am interested in your observations and photos of the birds when
you are able to observe them. It is an interesting problem to sort out
