We just brought four new cockatiels home, about 10 minutes ago!  They are a prolific breeding pair with two six-week-old babies.  The previous owners told us that the female is bossy, and wants to be in charge of everyone.  The poor male is missing a bunch of feathers on his head, so on one side he looks like a very strange vulture.  The poor guy is hen-pecked.  I just hope the 'hen' doesn't try to peck me too!  

We recently ordered some bird/parrot training material.
