Any ideas what this is?

Looks like a jungle pattern!

I've seen variable pastel patterns in the same clutch. I'd still say pastel, just not the same pattern as the others.

However, it's definitely nice and would make a great hold back. Breed it back to the parents if you can, maybe something will pop out.

The belly is mostly clear, just some faint speckling toward the vent. I'll definitely hold her back and breed her back to dad. Who knows, probably nothing big but time will tell....

a very bright normal..

It looks like a Pastel with no busy pattern. Although couldn't this also be some type of form of incomplete-dominance?
