SD's are known for having an off-the-charts food response. I would try feeding her every five days, she's still young enough to eat that often. Leave her to digest for 2 days, then handle on days 3, 4, and on feeding day before you start thawing her evening meal.

They are also known for being much more defensive than other retics, which makes sense when you consider that they stay small - and are thus tempting prey - for a longer portion of their lives than the mainland strains. Small locality boas exhibit similar patterns compared to their larger BCI cousins; my Tarahumaras were defensive, hissy, and nippy for two years before settling down.

Hook/tap training should have been started the day you got her, I do it with all of my larger snakes and also even with one of my bigger female king snakes. No I'm not afraid of taking a hit from her, but her thinking that my pinky finger is a rat pinky has gotten old. Hook or not, I'm not crazy enough to put my hand into a retic enclosure once I've started thawing feeders.
