I recommend reaching out to Bob Vu. His store is Bob’s Balls and his contact information is on his storefront. He has hatched a lot of orange dream pieds and can give you some pointers.
In my personal experience, orange dream pieds can be difficult to identify. Also, I’ve noticed that sometimes pied het ghost animals are brighter than their non-het ghost counterparts, so you have a confounding variable which could be affecting brightness.
But yeah, message Bob. He’s not in the forums but he’d help you on Facebook or through the marketplace (Facebook is probably better).
