Precautions for raising chickens in hot weather

First of all, a note about the climate controller, it can help the breeder better manage the house, but many breeders may not fully understand the role of the climate controller, one of the key points is: the ventilation of the chicken house cannot be used all year round A set of environment controller parameters is realized. That is to say, we must set different environmental control parameters to meet the needs of chicken growth in different seasons and stages. We recommend at least four program settings for the environmental controller to cover the winter brooding and growing phase, and the summer brooding and growing phase. However, even in the summer growth phase, we need to adjust the parameters to different degrees for 3-week-old and 6- and 7-week-old birds. There are two main risks for the summer growing season: either entering the tunnel too early will overventilate the chicks, or entering the tunnel too late will underventilate the larger chickens.

How much higher should the house temperature be than the target temperature when transition ventilation is switched to tunnel ventilation?

When excessive ventilation cannot balance the temperature in the house, switch to the tunnel ventilation mode to produce an air-cooling effect. Chicken weight, age, breed and feather level all affect the temperature setpoint for the transition tunnel. In general, older birds can enter the tunnel at 3°C above the target, which research shows is only beneficial for the birds. For young birds, we wanted the temperature to be 4.5°C above the target when entering the tunnel, as younger birds are more likely to dissipate heat and entering the tunnel prematurely has not proven beneficial.

Some farmers enter the tunnel when the temperature is 3°C above the target temperature, while others enter the tunnel when the temperature is 5.5°C above the target temperature. If we just want to use one number without taking into account factors such as the age of the birds, both numbers may be a bit extreme. Therefore, the main factor of age should be comprehensively considered when using it.
