I got a male and 2 female toulouse from Metzers and they were banded as to their sex. One that was banded as a female is the largest and has 2 lobes and the other 2 only have one. They are only 3 months old and now I don't remember which one is the male of the other 2. She was the biggest one when I received them is the only reason I know that she is a female. I wondered if maybe she was a little older than the others. Other than their size they all look alike to me.
