Temperature management Temperature plays a vital part in egg production. Too low temperatures during the first few weeks can affect your hen's production during her entire egg-laying cycle. At a later stage, the temperature does not have that large effect, but extremes should be avoided. Free-range hens need shelter for the night as temperatures can decrease drastically. Age Cage Rearing (°C) Free Range rearing(°C) Week 5-72 18-20 18-20 *Body temperature for chicks can be about 40-41°C Ventilation The function of ventilation is not only to supply the hens with an adequate supply of oxygen, but it also assists with the removal of waste products, growth, and combustion from the environment such as: Moisture removal The provision of oxygen to meet the bird's metabolic demand The control of relative humidity The maintenance of good litter conditions. Always ensure that there is a good supply of fresh air at all times, but be careful not to have a cold draft blowing into the brooding house as chicks are more sensitive to cold. Good maintenance of house curtains (if hens in battery cage) are needed. Free-range chickens tend not to have any problems with ventilation.
