I'm not sure what Hoobly is.. lol
I guess it's kind of like a Kijiji? if so yep you get ALL sorts on there.
I'm guessing a good few would be BYB, There is a BYB in my province who sells Chi's and she keeps all the girls until around 8 or 9 mos and spays them before selling them.
Your not nuts, I've seen the girl shortage as well.
