Do calves need to be kept warm?

This principal is the same for hutches; the air inside must be warmer to rise and mix with the outside air.
What are calf jackets for?
Calf jackets keep calves warm in cold weather so they use their energy to grow rather than to stay warm. They are most often used for calves from birth to 4 weeks old. If used correctly, calf jackets can save you money on feed, medication, increase live weight and reduce deaths due to scours.
