My 2 had so much fluff last winter that when twinkle moulted this spring I kept weighing her because I was sure she was loosing weight, she wasnt but she went from looking like a snowball, shes a rew, to looking like she needed a good meal.
They are both fluffing up nicely this week. They sit in the garden and 'puffle' Twink does it more than Ozzie, they sit and tuck everything in and then somehow their fur just fluffs up, it puffles:lol:
The lowest its been overnight in the shed is 2deg, but as they spend most of their time once its bedtime sat on the floor of the aviary I reckon they will be very very fluffy this year as they didnt have the outside option overnight last winter.
