males split for opaline

[mawwmd]

I am setting up a stud for classic and spangle rainbows. One of my first chicks( in nest) is spangle yf cobalt greywing, but also has a few blue feathers at the shoulders. could this be a male split for opaline? Mom is sky yf opaline greywing, dad is cobalt dilute spangle.

here is another green male(left) that shows the same thing, while my green hen has normal markings

update! chicky baby is also showing a bit of blue on the front edge of shoulder. I think he must be a full opaline or she is opaline so dad must be split for opaline.

I am sorry no one has replied to you yet mawwmd

Most of our members who are experienced breeders dont come on here so often these days

Dunno if Hezz or Marianne Marlow could help here?

I'm afraid I wouldn't be able to tell if a bird was split for opaline. I don't know much about the genetics side.

just found this old post on the same subject. seems that males split for opane can have some colr breaktrhough as a small amount of opalescense in the wings.
