Estimate age for my BP

I've got a female normal bp, she weighs 150 grass and is just over 2ft long how old could she be ???

You can't accurately guess age for reptiles. They all grow differently based on the conditions they were raised in. I've seen underfed snakes be that size at a year old even. The only way you'd know for sure is ask for the breeder's records.

She's likely less than 6 months old (and possibly only a couple months old), but as the above reply says, it's hard to say for sure because there are so many factors that go into their growth rate.

My snake wasn't 2 feet long until she was over a year old, so you can't really tell.
