It's Day 14 - super excited to candle the remaining eggs: Svart Honas, Appenzeller Spitzhausens, Silver Sebrights and a Cream Legbar/Olandsk Dwarf cross. Because the breeders shipped extra, the amount left is closer to the amount I was planning on hatching.

Candling results: 13 eggs look excellent, with a healthy network of veins, and active moving chicks.
One egg has a blood ring, and is going out. Two more are almost certainly done, and I'll probably toss them tomorrow after a re-check. The only remaining egg from the original Olandsk-Legbar cross looks uncertain, but two of the little eggs from the following generation look okay, so I may get to see what those hybrids are like.
Although I'm looking at no more than a 40% hatch rate, I feel happy that I have a couple of viable eggs from each breed. It's a little crazy to have to incubate nearly 30 eggs to get 4 hens, but between the perils of shipping and the reality of cockerels, that's kind of how it's working out.
