A childhood belief about birds

when i was younger i wanted a pet but we werent allowed so my older brother told me that if you get an egg and wrap it in a warm towel or keep it warm using your body heat then it will turn into a chick. i fink he said to hold it for like a whole day or something. during this time i wanted to check if th chick was actually growin so i cracked it to see if ther was a lil chick fetus thing there and when there wasnt i started all over again. ya i tried for AGES and needless to say there was no chick. :(
