HI!My two buns live outside all year and have grown lovely fluffy coats for the winter. BUT.iv never been alive when the temps have dropped this low (-11 last night)and im really wondering if they will die. They live in an entire garden shed and have hay and straw, i tried putting hot water bottles in but they nibbled them and popped them, tried wheat bags-again nibbled them!so im not sure how cold is too cold. During the day they just sit in the snow!When i bring them in the house they are sooo stressed and are like glued to a spot for hours on end and i dont want their coats to malt too soon. Sorry for rambling, in short, how cold is too cold?1
