I had asked this question earlier and found my answer. Found this info on https://www.cuteness.com/article/give-egg-heat-incubator. Find a Substitute Mother Step 1 Place an egg underneath or slightly near a hen inside the nest. Step 2 The hen will instinctively roll eggs in her nest under her body. Step 3 Eggs will receive heat naturally and then the hens adopt the hatchling. Use a Towel Step 1 Place a medium-sized towel in a cardboard shoe box. Step 2 Set the egg in the middle of the towel. Fold the towel around the egg. Step 3 Place a desk lamp with a 40-watt bulb next to the box. Plug in and turn the lamp on. Leave lamp on 12 to 16 hours daily. Use a Heating Pad Step 1 Place a heating pad on a heat-resistant surface. Step 2 Turn the heating pad to the lowest setting. Step 3 Place the egg in the center of the heating pad. Fill a Tube Sock with Rice Step 1 Fill a tube sock with rice. Tie the end with a piece of string to hold rice in the sock. Step 2 Place rice-filled sock in the microwave. Heat the sock on a medium setting for one minute. Step 3 Set egg on a saucer. Wrap sock around egg. Repeat when sock cools to room temperature. Use Disposable Hand Warmers Step 1 Open the disposable hand warmer package and activate the hand warmer. Set the hand warmer on a saucer. Step 2 Set the egg in the center of the hand warmer. Step 3 Repeat with a second hand warmer set on top of the egg. Change hand warmers every 10 to 12 hours.
