How do i know the chick is forming in the egg and is alive

Question

i have an egg i look at the bottom and there is a dark spot does that mean its alive

Answer 1

Ok if this is a a egg you got from the store then it is processed and that means that it cant be. Eggs from stores have g*y spots because they are old. Plus eggs in stores have not been sat on because they take them away before the chicken can sit on it. The chicken has to have 12 eggs before it can sit on them.  

Answer 2

umm i think after a while you will be able to shine a flashlight thru it and you can see the outline of the baby bird. good luck tho!

Answer 3

You should also see veins. If so then yes the egg is fertile. Is it alive? you wont be able to tell yet
