A childhood belief about birds

When I was young (about 4/5), I used to believe you could hatch an egg by putting it in a towel and keeping it warm. I came up with it after talking about it with my best friend at the time “Thomas”. Both of us took an chickens egg out of the kitchen and tried to hatch it. We stuffed them in a bunch of towels and took the eggs everywhere. And I literally mean everywhere. We brought the eggs with us in a bag stuffed in towels to: school, daycare, when we were playing outside and so on. We checked our eggs everyday to see if they were already hatching and to see if they had any cracks and/or tears. We also replenished the towels everyday so they would stay clean, but before we would change the towels, we would warm the new ones up so the egg wasn’t going to be wrapped in cold towels. After a week or so we started to notice nothing was happening, and we were wondering why the eggs weren’t hatching. We were convinced there was something wrong with the eggs, so we took our mom’s to the supermarket to buy us some new eggs and tried again. A week later the eggs still didn’t hatch and our moms told us that eggs out of the supermarket wouldn’t hatch because they sort the eggs that contain embryo’s out of the packages and throw them away. After that we became mad at our mom’s for letting us take the eggs everywhere and why they made us take all the effort of trying to hatch them while they knew they wouldn’t hatch. For years I was convinced I could make an egg hatch by putting it in towels if I could just get my hands on a “good” egg.
