I am on day 19 with a batch of chicken eggs. I'm down to three. I put them into lockdown yesterday with all three showing movement. However we had a power cut today while I was out for approx 3 hours. Temp got down to about 27 degrees. Please tell me there's hope :-(.
you are fine- the eggs will just be delayed for as long as the power was out. the power could be out for 12 hrs. Now that being said, I don't know if this statement is only good for younger developing eggs, because hatching time is very important. but 3 hrs. is really not that long.
