Buy a bag of feathers from your local craft store. Use the feathers to line the cloth ring in the middle of the box. Feathers store heat well, and will help the eggs stay warm. The number depends on how large the stuffed animals are and how much room you have in the box. Arrange them around the circumference of the circle to enclose the egg more for warmth. Make sure the stuffed animals are big enough to press against the sides of the shoebox and push the rags and feathers closer to the eggs. Place it in the corner of the box to prevent spills. Refill the water daily or as the water level goes down with evaporation. Check the water at least twice a day. Look for an inexpensive one at charity shops or garage sales. For a high-quality lamp, shop at your local pet supply store. Buy a lamp with an adjustable neck that you can reposition to achieve the ideal temperature. Make sure the heat lamp does not touch any of the flammable materials in the nest box, as this could cause a fire. Digital readouts make it easier to track temperatures to the tenth of a degree. You'll need this kind of precision when incubating eggs. Look for these instruments in any big box store. Many locations sell single devices that measure both temperature and humidity. Position the lamp so that the light is shining into the box. Place the thermometer and humidity gauge in the location you'll place the eggs. Aim for a temperature of about 98.6 °F (37.0 °C) and a humidity level between 55 and 70 percent.
