This is my first hatch. During the first 20 days, I checked the temp/humidity gauge 1-2 times per day. A friend of mine, who set the eggs the same day was getting pipping and chicks on day 20. That prompted me to really check the temp more than 1-2 x/day and I noticed that my temperature in the incubator was fluctuating every couple of hours -anywhere from 96-102- without me opening the incubator or doing anything differently! I did have 2 hatches recently..both were 1 day late. The chicks seem weaker than my friend's chicks. I am now awaiting the other hatches -but I have a question: At what point do I toss the eggs and call it a day? How much does this temp fluctuation affect these chicks? I'm concerned that they will all be weak and/or deformed due to the temp problems, and I can't help feeling guilty for not catching this problem sooner.
