These are adorable! Good to know they made the journey! I believe so, I've hatched eggs that were out on a 21 degree day. I just put OE eggs under my broody (shhhhhh! don't tell DH). Some of the eggs I had soaking in water first, this is supposed to not hatch, so it's a test run. I marked those eggs with a 'W" so I'll know. BTW Sally, those 1/2 Marans chicks are toooo cute! LOVE the coloring coming in on the wings.
