Candled this morning (day 9). Out of 8 buff silkie eggs, 7 had visible veins and dark masses, some you could even see the embryo moving! 1 was clear, so its getting tossed. All 4 black/blue/splash eggs are developing, and 3 out of 4 white eggs are as well. So 2 clear out of 16 eggs, which were shipped during some very cold days, I'd say we're doing well!
