I'm ordering some silver laced cochin eggs off ebay, but I believe that they will come too soon. For the hatchalong, I plan to add some silkie eggs from my neighbors to the incubator with you all. The catch is I'm doing a little experiment, I want to watch an embryo develop. I have a few ideas in my head, all of which involve removing the top half of the shell around the air sac, so that the clear inner membrane remains intact. I then am going to cover that membrane with clear hot glue to act like a "shell". I was also thinking of covering a different one with clear nailpolish. Another idea is using clear candle wax to act like a "shell", and finally, I will also simply cover the top of an egg with sarran wrap to act like a "shell". I won't do this to all of the silkie eggs, just a couple to see what will happen. What do you think?
