Is there a way to tell if feathers were naturally molted?

I ordered parrot feathers as a gift for my gf to use in crafting, but I’m worried about how the feathers were acquired. They say they were all sourced ethically and molted but it’s an Etsy seller who also sells a few (non parrot) pelts.
I brought these concerns up with her and we are both now uneasy about keeping the gift and if there’s no way to tell, we’ll just return them.
