So I have tried the Wax method to save a cracked egg.
It was a shipped egg, & when I candled it had a huge crack & nice veining so I left it in trying to decide what to do.
It is a really nice choc. egg & tonight I candled & it has a live growing embryo I can see even in this fairly dark egg.
So I took a deep breath, found a pure beeswax candle I've been saving for years for "something special"
& a few hot fingertips later the HUGE crack is totally covered in a line of wax.
I know the odds are all against this egg, it was shipped, it is cracked basically end to end long ways.
& I should have found the crack & waxed it prior to setting to seal out bacteria which likely it is full of.
But I've tossed 16unfertile eggs, & 2 good looking eggs w/ blood rings in 2 days,
so here is this lovely choc. <cracked> egg w/ a dancing embryo just doing what it can fighting to make it to hatch,
so Best of Luck little fighter, I've made up for your shipping crack w/ the best wax available, now becoming a real live hatched chick is up to you...
