There is a CAG breeder near Joliet IL that sells red factor.
She does not charge more for her birds, but I think she has a
waiting list for females. She had a nice male "on sale" last
month. I think she was asking 800, It had a lot of red
peppered all over. I do not know if she will ship
I can try to find out who she is if you have any interest, she
does not come to the Joliet bird fair often as she does not
have many "extra" birds
In this area CAGs range $700-1200 fron a private party
More in a pet store $1200-2000
I would buy from a good breeder, not a pet store.
