Thanks to the K&H Pet Products Thermo-Chicken Perch you can say good-bye to frozen toes! Most birds being covered in their own down blanket lose a lot of body heat through their feet. In extreme cold weather, the K&H Thermo-Chicken Perch can be invaluable to your flock. The gentle warmth provided by the perch aids in the retention of body heat. The perch warms the entire body utilizing the bird's own circulation system. Dual internal thermostats regulate the perch to the perfect temperature, day, and night. Warm perch = happy birds!
