I have lost 3 today. There is only 1 left. We moved the cooler into the laundry room where there's more heat. The kits lost weight when I weighed them these morning. They where all alive. We put my hay in there in afternoon to try and keep warm. It was in 30 today very cold and doors where open and closed all day on washing incubators and my sons class it was very busy. Black 1.1 black 1.1 pink 1.0 pink 0.7 lost all but pink 1.0 her weight stayed the same. The heater stoped working. My parter tryed to put pc pipe in the drain of the cooler to hide the cord so she couldn't eat it again. Bad rabbit.
