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.
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")
- 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 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.

Both incubators are heated by a commercially available glass-covered heating element. For the plywood incubator, it should provide 160 watts of heat. Slightly less heat is required in the polystyrene incubator.
In 2019, Mississippi’s agricultural industry faced the prospect of dipping below $7 billion for the first time in eight years, but federal payments pushed its value up enough to post a slight gain over 2018.
The estimated value of Mississippi agriculture in 2019 is $7.39 billion, a 0.2% gain from last year’s $7.37 billion. Included in the total is an estimated $628 million in government payments, the largest amount of federal assistance Mississippi producers have seen since 2006
Overcoming every challenge that comes its way, Mississippi’s poultry industry maintained its 25-year streak in 2019 as the state’s No. 1 agricultural commodity.
In a state where temperatures exceed 90 degrees more than 100 days a year, heat control in poultry houses is a very important consideration for Mississippi's biggest agricultural industry.
Poultry producers got off to a robust start in 2018, which helped the industry end the year strong.
