They are GREAT starter snakes.
But...they do require proper care, knowledge, and attention. They have specific needs (that are very easy to meet once set correctly) and generally low maintenance pets.
That being said, you shouldn't own one illegally in any circumstance. This snake may have been sick a week ago when you got it, it may not. It may have been induced by the stress of moving. Have you contacted the breeder? Regardless, sick or not, stressed or not, you really honestly shouldn't have it.
