Hi,
18 shipped silkie eggs
9 fertile
9 had lots of air bubbles or porous looking shells
Of the 9 fertile all 9 hatched, 8 lived.
I ordered my eggs from the next state over (GA). The city I got them from is not too terribly far away from the border of SC and GA.
I would recomend getting eggs as close by as possible. The further they travel the more chance of non viable eggs.
Best wishes!
