I have two silkie eggs in my incubator. throughout incubation they have developed at the same rate, but as of yesterday I have noticed that one egg is developing much faster and the other is rather see through with veins that seem to be receding.The embryo is still moving and kicking. Its not dead... I haven't been able to find any pictures of vein patterns like this anywhere online. What do you think? Extra info: They are the only 2 of 9 shipped eggs to get to day 18. I had two early deaths and the rest were scrambled yolks. All of the eggs had loose air cells and the two survivors' air cell didn't completely reattach until after day 7. I have them set point-side-down in chopped up egg carton and tilted 3-7 times a day. They are being incubated in a homemade forced air incubator with a water-heater thermostat, two light bulbs, three thermometers, and two hydrometers. the average temp is at 99 *F and 50% humidity. The last week because the air cells grew a little too fast during the first week at 30%.
