Color/ Phenotype Identification

[JKTM]

Good day, Sir. Once again, I'm asking for your help in identifying the color/ phenotype of my racing homers.

Photo #1:
- Young bird (less than a month old)
- I'm not sure if it is a homozygous indigo or an indigo with recessive opal.

Photo #2:
- A fledgling (more than a month old)
- Same theory with the young bird in photo #1.

PS:
- Both birds are siblings.

Thank you!

I think indigo with recessive opal, but I'd be more confident if we saw them after their first moult.

Thank you, Sir. Happy Holidays
