For the most part,and I'd be wary of a $50 plucked bird myself
too,how did the poop look?
When I had all my Sennies s/s (I had 8 pairs at one time,they
were so cute!)..it was pretty accurate about the yellow tails,but
one thing I noticed,when not breeding,the males looked alot
duller,and could have been mistaken for females if not careful.
There was a rather rude individual that used to post on here
constantly that CAGS were dimorphic as well,but I personally have
seen that proven wrong.
