I'm not a BP breeder but I've had some BPs over the years, both c/b (I bought) & w/c (turned over to me): The largest BP I've had or seen was a w/c import female,
hefty & about 5'. No idea of her age, of course; I got her from a family whose kid lost interest after they got her from a pet store the year before (& I KNEW they were
selling w/c). She survived the kid's ignorance & did well with me, despite the hundred or so ticks I removed from her...they "didn't know those were ticks, they thought
they were just scales" and then she had no heat for a while too, after her "hot rock" broke.... She sure was a survivor.
