I found this on a web site. I am thinking about trying incubation. I thought this would interest someone. It kind of freaks me out Shell-free Cuture System Procedure Eggs must be at 72-hours of incubation, or the yolk will be too fragile to be transferred without breaking. 1. Fill a plastic cup with an inch of water. Place a sheet of plastic wrap over the top of the cup, letting it drape down a bit. It must be secured with a rubber band to hold the plastic wrap in position. 2. Trim away excess plastic wrap around the rubber band. (If plastic is not trimmed, the egg albumen will wick out of the container creating a mess in the incubator and reducing the embryo survival) 3. Obtain a 72-hour egg. Wipe the shell with 70% ethanol and allow it to dry. Hold the egg horizontally for 1 minute to allow the embryo to rotate to the upper side of the shell. 4. Carefully crack the egg as if for frying and let the contents drop onto the plastic wrap. Try to crack the egg gently but firmly so that a single large crack is produced. DO NOT BREAK THE YOLK. If the yolk breaks, there is little chance that the embryo will survive. 5. Look for the embryo. It may have ended up underneath the yolk. It usually will float to the top of the yolk within a few minutes. 6. Cover the entire assembly with a 100mm-diameter plastic petri dish lid. Place the culture in the egg incubator (at 38 degrees Celsius). Observe the cultured embryos daily. As the embryo develops, note especially changes in the eye, limbs, and extra-embryonic membranes.
