I didn't mean any offence to my post. But if you listen to Ernest, he states that it's an '06 and it still has a couple years until it reaches breeding size. From everything I have read, a female RTB should be ready to breed at around 3 years of age. IMO, it was underfed, that's how it stayed so small.
I by no means believe I power-feed my boa. She's an '08 and nearing 5'. I was giving her 2 medium rats and now she's on 1 large rat because after she would eat the two mediums, you couldn't even tell.
Good pick with the Nics, also be sure to check out the hogg isls. They were on my list before an RTB.
