Welcome!
We just did the same thing! Please feel free to check out my posts and the other posts for hatching silkie eggs! These folks on byc are the best! I hope you get 100% success!
We had sizzle and silkie eggs, 6 viable and only 1 silkie hatched successfully and 2 sizzles. Our silkie eggs were from ebay too. When we candled the eggs the silkie eggs were very thick and nonporous. We made a big mistake of putting the eggs on day 18 in a Styrofoam container. Another silkie tried to hatch and zipped but the eggshell got stuck, it adhered, to the egg carton. If we do it again and it gets that far we will intervene if it stops peeping. I found that blunt forceps, aka pick ups/tweezers and iris scissors really allowed intricate penetration of the outer shell without compromising the innermost membrane. I utilized the iris scissor to make a small puncture hole in the air sack region and worked the area away from the bird with the pick ups. Unfortunately the birds had expired prior to intervention. I had these instruments around the house but it would seem that any sharp tipped scissor could work as well. Of 3 late deaths 1 should have survived but I failed to intervene in time, and 2 (and a sultan) were late deaths that failed to pip.
How many will you try to hatch? What colors are they most likely going to be? So eggcited for you!
Happy hatching!
Please update as you go! What incubator are you getting?
