So, it seems like I won't be able to buy off of the woman I was talking to via email. She had an ad on Craigslist saying that she was selling. However, every time I brought up wanting to buy a female off of her (even after she said she had a few females to sell), she would just ignore my questions and talk about something else.
It seems like my poor little boy may just have to wait until after winter to get a mate. I can't help but notice though that he has calmed down significantly. He's no longer calling out often. I might hear him once, maybe twice, a day. Even then, his calling out usually seems to be in response to something (Firetruck sirens, the chirping of the Carbon Monoxide detector as it's plugged back in, that one car insurance commercial with the baby chickens, etc.). He's also no longer jumping around his cage at night. In fact, at night I can find him settled down in one corner of his cage.
