Me and my granddaughter who is 4 years old, Were gathering eggs yesterday. When she asked me if the eggs had diddies in them, and I told her no. She said of yea I forgot, they have to be Baked. She is my little helper she marks the egg's, and then put's them in the incubator. Then when hatching begins she has to take them out. You should see her with the babies, she is so kind and gentle with them. Just wanted to share this.
