Hey guys, official update:

Fawn still a sausage.
Fawn currently mid-shed (last shed around 15/12 ... one month ago - normal shed cycle every 3months) and has refused food today (something not in this girls character as she'll normally take food at any time).
She also hissed at the food and struck at it (ie ... "Leave you alone you fiendish morsel of food!!!!")
weight progression - mid-2011 - 253g
