Farrier that's basically it here too. Too often hens have hidden and started eggs - shame on them, so I get staggers from my own eggs frequently enough that I now candle more than I normally would trying to catch those few in a batch that some evil hen pre-started.
It's a lot simpler with shipped or single source eggs.
But I've gotten used enough to staggering that I compensate and go on. LOL. I just bumped humidity in Darthbator because of the three that are early, the seramas not due til Fri, and a few test sizzle eggs after that. (yes, couldn't help myself).
The eggs in the Redwood Goliath are due around Friday - but they're found eggs, they hatch when they hatch.
