I was just given 5 partially incubated bantam eggs... the nice lady I got them from wasn't sure how long a hen had been sitting on them. I got them home as quick as I could, and quickly candled them before getting them in an incubator pronto to get them back to ideal temperature. One in particular was really developed... I could mostly just see a dark mass, part of a beak (?), and an air pocket. The other looked pretty developed too, though perhaps not quite as fully dark. All had big air cells though. Looking at all the candling photos I'd guess they're 14-18 days along. So I'm not sure how to treat them. Lock them down? Keep rotating? Any words of wisdom? Thanks.
