Well, I do appreciate the response and now I can add some info that may be helpful --
That precious, darling, sweet puff-ball that I vowed to have 'forever' turned into the most evil creature we've ever had -- ever!
A rooster, of course, and 'bad to the bone' -- he was about the size of a sparrow under the lovely 'frizz' -- the hens ganged up to try to 'beat some sense' into him and he fought back with every fiber of his tiny being -- blood was shed and wounds were treated --- there was an expensive vet-trip --
My husband, who fancies himself as some kind of 'animal whisperer' was attacked again and again -- we soon were very much afraid of 'The Frizz' --
embarrassed, but still afraid ---
I found a home for him with a guy who wanted him for breeding (The Frizz was a stunningly beautiful bird) --- the first day of free-ranging at his new home, he chased off two huge hawks who 'never looked back' and then decided it was his job to guard the property and the last we heard 'Frizz' was stalking about looking for trouble --
maybe that's the way to determine sex of a Frizzle -- choose one that is the cutest, sweetest, etc, and then 'stand back' to see what happens -- but don't get too attached!
(And this is only one of two critters that we ever re-homed -- the other one was a dedicated 'broody-hen' and she went to a spot where she could raise babies to her heart's content -- every cat, dog, horse, bird, fish, turtle, etc. etc. etc. that we have added to our family has stayed until it died at a great age -- The Frizz was the exception --)
Good luck to all who have Frizzles!
