I've candled a set of Trader Joe's fertile eggs that I'm incubating - day 6 today - they all look like they have good vein development but I've only seen an actual embryo in a few of them. The rest it looks like I'm seeing the amniotic sac, in some cases moving, at the center of where the veins branch out & right next to the air sac, but not the actual embryo. These are white eggs. I'm hopeful that this is a good batch (I've tried a few times before with TJ's and had little or no development) & maybe I'll see more in several days. Just wondered whether anyone had seen something like this before. I haven't seen it on my previous batches (not TJ's eggs).
