do not I repeat DO NOT crack an egg open until you are sure it will not hatch...after 2 hours of crying my eyes out .....calling myself a baby chicken killer......I am able to type to anyone that cares......do not crack an egg unless you know it is a dud. I cracked one one the 22nd day...wanting my lone chick to have a friend....and the little bloody mush in the egg was still beating.....I am a baby chicken killer. eeek!!! I will not touch the other eggs for days now. My heart hurts and I learned a leason.....so did my little son (9 yrs old). I feel so bad....my family seems to understand but i cant get that image of the little beating mush in the egg that I CRACKED open. now....I still have a lone chick that keeps crying ~Tiff~ wow, I havent cried this much since I scraped up my cat(that I bottle fed from 3 days old) that was slung all over my back yard, guts everywhere a year ago, trying to clean it up before the kids got home from school.
