Manufactured from high quality, tough, durable and impact resistant polyethylene the Replacement Calf Hutch Vent Cap comes complete with a securing stainless steel bar and locking clips. The vent cap on the calf hutch is an essential piece to allow air flow through the hutch helping to minimise condensation in hotter weather and ensures the calf doesn’t over heat during the day or use vital energy at night to keep warm helping to increase weight gain of the calf.
