There is no way to tell without a DNA test, which is about $30-35 around here. I've had 3 very loud females in the 4 females I have owned over the years. His/her orange patches are light colored which means female, but it's not for sure. Out of those 4 females 2 had dark patches and were loud. I really thought they were males, but DNA tests confirmed they were female. Only laying eggs and DNA tests are for sure.
