Fumigation and sanitation of hatching eggs

Sanitize eggs and equipment before storage or use by fumigating. Under-fumigation does not kill the bacteria, but over- fumigation can kill the chick embryo in the egg. Use recommended amounts of chemicals at the right time for the length of time specified.

A room or cabinet large enough to hold the eggs is required. It must be relatively air tight and equipped with a small fan to circulate the gas. Calculate the inside volume of the structure by multiplying the inside length by the width by the height.

Stack the eggs inside the room or cabinet on wire racks, in wire baskets, or on egg flats so air can circulate among the eggs. Remove eggs from the cases for good air circulation. Formaldehyde gas is produced by mixing 0.6 gram of potassium permanganate (KmnO4) with 1.2 cc of formalin (37.5 percent formaldehyde) for each cubic foot of space in the fumigating structure. Mix the ingredients in an earthenware or enamelware container with a capacity at least 10 times the total volume of the ingredients.

Circulate the gas within the structure for 20 minutes and then expel the gas. The temperature during fumigation should be above 70o F. Allow eggs to air out for several hours before placing them in cases.

Additional information on hatching egg sanitation and fumigation can be found in Hatchery Management Guide and Care and Incubation of Hatching Eggs.

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.

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.
