My best hatch was from my pullets that had only been laying 4-6 weeks at the time I collected. 21 went in, one quite by day 5 the rest made it to lockdown and hatched perfectly. If the size of the eggs are decent and the pullets egg making is all kosher, then there shouldn't be a problem. I don't know if shipping with pullets is any worse than shipping with more major eggs though.
Still air should be 101-102 taken near the tops of the eggs. Humidity is finding what works for you by monitoring the air cells or weighing the eggs. I am not comfortable incubating at less than 25% or higher than 40% for the majority and only adjusting on either side of those numbers if the air cells signify I need to and then only temporarily.
I want a baby dragon!
For one, exploding eggs though they can happen are not all that common, especially later in the hatch. Chances are (not always, nothing is certain) you will smell a bad egg before it gets to the eggsplosion point. Everyone knows I love to candle. I candle (a few, not all) every night when incubating to get my fix and spot check. But here's the thing: I don't do shipped eggs, (yet anyway). Even I understand and admit the logic behind less is better for an egg that has been abused through the postal service. In all honesty you think you maybe protecting yourself from a bad egg episode, but you may be weakening an already weak egg. Now you can do what others do and take the theory that you only want the strongest and enable your candling more or you can side on the giving them the opportunity to strengthen by lessoning your intervention thus giving them slightly better chances. I always say to do what's comfortable for you [the hatcher] if it's working no matter what anyone says, but I also believe that if something isn't working you should probably change your methods-at least for the changing circumstances.
