I am new to rabbitry, and have 5 Flemish Giants 7 weeks old. They will be show rabbits. Their rabbit shed gets as warm as 85 degree. I have noticed some of their ears have started folding over. I brought a few in to see if that would stop the folding, they started folding over week ago. Does anyone know if this is now permanent are will they straighten back out, now that I have them in a much cooler environment?
