Congrats!!!! Your iffy egg should be fine if it was brief! Let us know how everything works out!
Kept an eye on the egg with it's little pip hole and about 12 hours later -- after being kicked all over the incubator by its brethren -- it started in earnest banging hunks out of the shell. By the time our dinner was done the chick was standing and swaying with its feet under it. So got four BLRW chicks! Quite happy about that and that there was no assisting necessary. Dropped the humidity down in the Brinsea and will move to the brooder tomorrow (and, of course, take pictures)
Candled the White Marans and there's four that are in really good shape (veins, proper darkening) and still a couple of days before Day 10 official candle...but sometimes with those dark eggs you just cannot tell until just about lockdown.
