I have an egg that I decided to glue and patch...just for kicks to see if it works.. i got a shipment of 6 eggs all were great except little "patch" lol, little patch when I candeled before they went in I would see a crack not visiable to the eye, i decide to break out the clear nail polish and lightly mend the crack and jsut go for it, no major damage right? next day I inspect everyone and candle "patch" and darn it another crack I didnt see at the bottom, break out the nail polish again, cover the cracks, welll dummy me didnt let the nail polish dry enough and patch stuck to the egg turner, POOP! , so I wiggle and wigle gently and unfortunately a piece of shell came off!!!! DARN IT but the membrane is in tact, shoot, lets get creative, i made a paper patch to go over the hole and used the nail polish again, fast forward 2 days , LOL patch is the first of all the 6 eggs show show visiable veins today LOL... im not holding my breath, but I jsut found it amuzing... had to share ...lets hope the best for patch!
