Classroom Power Outages and Tropical Climate

I think that the degree of temperature fluctuation will vary with the type of incubator. Will the temperatures typically be above 100F in your classroom? If not, then don't worry.

For what its worth, I had a 9 hour power outage about 2 weeks into my hatch and both eggs survived. I would not imagine that such short outages will make a significant differences. Companies such as Brinsea have an optional feature to be turned off for optional periods of time, to simulate a mother hen getting off the nest.

 

1-15 minutes isn't bad. Like CTKen some of the newer bators have "cool down" periods. Of course, it's generally once a day, imitating the fact that the mother hen does leave the nest. The internal temp of the egg takes longer to cool than the air temp, so een a drop in air temp for a short time, does not drop the egg temp as quick. Granted it's better without fluctuations, but I think even with the minor drops you should get something as long as they aren't lengthy. Being in a tropical climate, I would highly suggest running a dry incubation or "low humidity" incubation (if it's not a high elevation) and monitoring the air cells to know when and how to adjust humidity. Is the incubator you are using still air or forced? What kind of incubator do you have?

Eggs are amazing. I've seen people have 12 hour plus outtages and still have decent hatches.

 

I've lost power for several hours in both of my last hatches and something survived each time- first group was shipped eggs, and I had a terrible hatch rate, but in hindsight there were multiple problems. This last hatch, I lost power overnight, and 5/6 eggs hatched just fine (but a day late).
