Incubation temperature requirements
The incubation temperature requirements for most hatching eggs is surprisingly uniform. The eggs of almost all domestic bird species (and many wild species) can be incubated at the same incubation temperature. Therefore, eggs of several different bird species can be incubated at the same time within the same incubator.
The incubation temperature of naturally (nest) incubated eggs is controlled by the hen. The recommended temperature within an artificial incubator depends upon the type of incubator being used. If the incubator used has a fan for air circulation, the temperature must be adjusted to 99-100o F.
An incubator without an air circulation system requires a higher temperature. The temperature in this "still-air" incubator is measured using a thermometer with the bulb positioned at the same level as the top of the incubating eggs. The recommended temperature in this type incubator is 102o F.
The reason for different temperatures is that circulating air warms all points around the egg shell while still air temperatures are warmer at the top of the egg than at the bottom. Therefore, increasing the temperature at the top of the egg will compensate for the egg's cooler parts. The same average egg temperature of 100o F can be maintained (for the entire egg) if the higher temperature of 102o F exists at the egg's uppermost point.
Do not allow temperatures to exceed these recommendations, even for only a short period of time. Although it is not recommended, slightly lower temperatures will not kill the chick embryos, but can increase incubation times and produce weakened chicks. Temperatures only a degree or two above the recommended temperatures can kill chicks within 15-30 minutes, depending on how high the temperature is and the stage of development of the chick embryo.
In three days, Teresa Dyess shifted her business focus from produce to poultry.
The change began two years ago with an offhand remark from her husband, Joe Dyess.
“He told a broiler grower in Wayne County we wouldn’t mind building pullet houses because we wanted to diversify our farm,” she said. “We didn’t think any more about it, and then the next day a poultry processor called and offered us a contract. A banker came the next day, and everything fell into place.”
Lanette Crocker, coordinator for the MSU Extension Service in Wayne County, said Teresa Dyess’ adaptability has helped her maintain success through the farm’s transition.
RAYMOND, Miss. -- Mississippi's poultry industry remains healthy with a strong demand for broilers and a positive outlook for the remainder of 2017.
STARKVILLE, Miss. -- All Mississippians who raise any species of poultry are being urged to follow strict biosecurity practices and review new requirements regarding sales and exhibitions.
Tom Tabler, poultry specialist with the Mississippi State University Extension Service, said that while avian influenza is not a threat to human health or food safety, an outbreak would endanger backyard flocks and the state’s nearly $3 billion commercial poultry industry.
STARKVILLE, Miss. -- Families willing to host a flock of feathered friends reap the benefits of fresh eggs delivered daily just outside the door.
What started several years ago as an underground "urban chicken" movement has become much more common and widely accepted. Today, raising backyard chickens has gained popularity nationwide, boosted by interest in locally grown foods that avoid the energy use and carbon emissions typically associated with transporting food.
