hey guys and gals

just received my first pair of rosy boas. i am used to the bigger boids, but i am getting my daughter into breeding. the male is albino het for carson snow and the female is double het carson snow.
i was told they were 2008.
i am very new to the rosy and sand boas. (also got her some het anery kenyans) what is the adult size of these (average weight and length)? i do not want to attempt breeding this next season until i know for sure. they are close to 2 feet long. not currently sure of weight as i just fed them.
please any help will be appreciated. i am really getting into the rosies. its making the hobby exciting again. especially since i am passing it to my daughter and later son when he gets older.

thanks
Michael
