You chicken folk are far more full of knowledge than anyone I know.
Welcome to BYC Daddy Roo! and Oz's exciting journey/s! When the egg is frozen and cracks, I have had minor issues with cold eggs from the coops, sometimes when it gets extremely cold and the eggs do freeze you should candle them to look for cracks, when you bring them in the cracks can easily be missed by our eye, but a candle you should see the small cracks. Brinsea ~ Temperature Guide Links below on how to candle eggs,
The temperature at the lower end of this range is sometimes referred to as ‘Physiological
zero’ - the threshold temperature for embryonic development. Unfortunately different organs
appear to have different thresholds resulting in an unviable entity.
Zone of suspended development (-2°C - 27°C/28.4 - 80.6°F)
Below about 27°C (80°F) no embryonic development takes place. Prior to incubation, eggs
must be stored in this temperature range (preferably around 15°C/59°F).
Zone of cold injury ( -2°C/28.4°F)
Below this threshold ice crystals will start to form in the egg and permanently damage may be
done to internal structures. Eggs may lie for some considerable time in temperatures close to
freezing without suffering damage.

I am keeping a notes/links/ information page from that incubation thread to keep track of stuff on the thread so it can be found in our discussions...
this link is at the top of the OP/Original Post of the thread
I have pulled extremely helpful NOTES, LINKS &
Informational Post Links from the entire incubation thread
for EVERYONE'S convenience and will continue to put them HERE:
