You basically have to take the breeders word for it. To me they look like Asil mix from the photos you have provided. But a close up of the head, body and feet/shanks might tell us more.
Alot of folks mix different asil blood to try and find the "one". The Puerto Ricans are already a mix of asil (Rampuri, Argentine, Atkinsons, Paki, etc). Your pullet tails are too long to have much PR blood. The Boricuas like short tails on the hens. Some might say, the Argentine has less of a convoluted lineage, as many lines can be traced back to the ports of export/import. The Filipino asil is a new one to me??? Most likely another combo asil or quiet possibly a grade.
The bottom line is you are happy with your purchases and they will probably help with your Black Cubalaya project. Good luck.
