The rooster looks like a splash with red leakage to me. I could see salmon in the hens, but I wasn’t aware that brahmas had any sort of wheaten/salmon varieties.
Do you have a picture of these salmon splash brahmas? I ask because variety names could be misleading, so they could have different genetics than an actual splash salmon.
Light x buff - light hens and roosters who appear mostly light but have some yellow leakage
Light x dark - hens will either...
