Welcome to BYC! It’s nice having new members. You mentioned other breeds. Do you have others now? Are there any goats in your collection? We look forward to seeing more of you, and hearing more about your animals.
You could post photos of your Polish, at "what breed or gender is this." I would recommend waiting till they are 4 or 5 mos. old. In general a wild rock star crest is generally the mark of a cockerel. Females tend to have a nice full bouffant crest. Though nothing is written in stone.
