Does anyone have contact information for a reliable person/company that does DNA sexing? We just lost a swan to raccoons (32 days on the nest ). I thought we had banded our female, but the one that was sitting on the nest the most and was killed was the unbanded one. We had sent a gentleman some feathers when they were young and we thought we had a pair, but maybe we had two females? I just figure it will be easier to find an extra male rather than an extra female. Thanks.
