I would keep the one with the shorter tail, the APA SOP doesnt give a tail angle, but says that the tail should be angled so that it continues the concave sweep of the back. Other than the tail, are they equal in all other areas such as head shape, overall body shape, leg feathering, etc.? I have seen some brahmas that have the head shape of a plymouth rock. They should have blocky heads. Also something not as important as type is color, are they equal there also?
