Google to see if there is a Brahma club. Often the breeder clubs have a directory.
next, search the NPIP website. Last time I checked, you could search by state-this brings up a multi page document that looks confusing. However, it lists the breeder name and address, along with the breeds they have. The breeds are listed in code. So, to get the code for Brahma, go to left side of website and there will be a selection that brings up the “stock” codes. Look for the “R” prefix (or “W” for bantam) to find all Brahma codes. Search the breeder doc (use the “find” function on your computer) and it will allow you to easily find anyone that lists the breed as one they raise.
