12 12 LOHMANN TIERZUCHT › MANAGEMENT GUIDE › EARLY MANAGEMENT Early Management Empty house A full terminal cleanout should have been undertaken. Ventilation After achieving the desired temperature, let the ventilation work at its minimum level. This can help prevent temperature differentials in the rearing house. Feed & Water Ensure that feed and water has been dis- tributed evenly throughout the house. Water pressure should be lowered to allow water drop- lets to form on the nipple-drinkers which will help the chicks to find the water. Temperature Heat the facility to 35–36°C (95– 96.8°F). This temperature should be maintained for the first 48–72 hours. Air humidity should be at a minimum of 60 % (3 days + add temp/humidity table). Drinkers The height of the drinkers must be set at the correct height for the new flock. Drinkers You may need to change the water in the bell drinkers and/or flush the nipple lines to assist with this. Summer /Winter In summer, start with this 24 hours beforehand and in winter, 48 hours before the chicks arrive. Equipment Check all equipment for function- ality (feeders, drinkers, heaters, lights)! Water temperature Ensuring it is between the optimal 20–25°C (68–77°F). Lighting Ensure adequate lighting levels are set in the house. Try and ensure the light spread is as even as possible.
