Thats Crazy if they are All females!! I have 7 babies and so far only one has croaked. Meaning 1 out of 7 is male ( so far ). Is there a higher ratio of females to males? You cant tell when they are small so, people cant be picking out all the males. Is there a "natural selection" thing going on here?
Also, at what age do they begin to start croaking? I have one doing it now, will others follow? Can a male be shy about it? What are some experiences others have had with this? Please, I'd like to know...
