.......Why buy first, and ask questions later? Should it not be the other way round - well at least if you are a responsible owner. . . .
Yes in an ideal world we all do things in the right sequence, occasionally someone does something on impulse so lets not judge and just offer practical advice !
You said you bought a yearling yesterday, why is the photo dated 21/7/2007?
how is this snake still a yearling??
Maybe the battery went flat and she didn't bother resetting the date stamp, ! !
Dont handle the snake until it is eating
regularly (about 3 feeds), getting it eating properly is your first priority.
Leave the snake to settle in for a week before offering a feed. Once it has eaten dont disturb it for a couple of days while its digesting its meal.
a bite from a yearling will make you jump more than inflict any great pain, all bites seem to bleed pretty well and look a lot worse than they are.
How have you setup your enclosure ?
what temp is your basking spot and your cool end. if these arent right then it wont eat or if it does it wont be able to digest properly,
do you have a thermostat and thermometer set up ?
Maybe post a picture, its easier to offer help when the setup can be seen.
