Construction of a still-air incubator

Small incubators, suitable for use in the home, can be purchased from stores that sell farm equipment. An egg incubator can be built at home with a little work and expense.

The first incubator is constructed from a polystyrene ice chest. It is inexpensive, and because it is insulated, is inexpensive to operate. It can be damaged easily. The eggs and chicks can be observed through a window in the lid. This incubator will hold about 40-45 eggs.

The second incubator is more expensive, but is more permanent. It is constructed of plywood and glass, and will accommodate up to 100 large eggs. Both incubators are heated by a commercially available heating cable. The heating cable can be replaced with two or three ordinary light bulbs. Get a list of organizations that sell incubator supplies and equipment from your county agent or state poultryman.

 

Sytrofoam incubatorPolystyrene Incubator

You'll need the following equipment and supplies to construct this incubator.

  • Polystyrene ice chest (12-16" x 20-24" x 12"-15")
  • Heating cable
  • Micro-switch assembly (thermostat)
  • Glass (approx. 10"x14")
  • welded wire - hardware cloth (24"x36")
  • Cake tin (9"x14"x1 1/2")
  • Thermometer
  • Masking tape

Get all equipment and supplies before starting construction. Carefully read and understand the instructions. Expect to spend about 2 hours building the incubator and 4 hours testing it. A description of the construction process, complete with illustrations, is available online.

 

Plywood incubatorPlywood Display Incubator

This incubator is more expensive and will take longer to construct than the polystyrene incubator, but it is more durable. It is built of ½-inch exterior or marine grade plywood and glass, and will accommodate up to 100 large chicken eggs. Building plans for this incubator are available online.

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.

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.
