I Cisko Mclovin While I have not personally bred my boas (yet, but have plans for it once they come of age) my uncle has many times, and is friends with a reptile breeder/owner of a specialty store in Columbus, OH. He has bred boas many times, as well as a wide assortment of colubrids, ball pythons, burmese pythons, reticulated pythons, etcetera .Anyhow, they both agree that boa constrictor (red-tail boas) and boa constrictor imperator (common boas) can be bred at about 4.5 feet. This means the females could be bred at two years, but shouldn't be bred until three or four years (until six feet) or unless stunting is inevitable. Males can be bred at four feet without risk of stunting. If you hold any interest in viewing the website of my uncle's friend's business, it is
