Well, we were told that Teddy was a DNA sexed male, but the previous owners didn't have any paperwork. I decided to go ahead and have him sexed, just so I had confirmation/something on paper. Avian Biotech emailed me the results today and Teddy is a GIRL!!!
Poor little thing has spent the past 2 years being called "he"!
"Teddy" is now "Teddi".
