I think I made some big mistakes with our homemade incubator for my daughters science experiment. I think my current hatch is not going to work due to the following mistakes: we didn;t calibrate our thermometer We got Americana Hatching eggs I put all my Hatching eggs in at once 5 days ago my incubator was a steady 99 degrees so I put a dozen eggs in the incubator. I started to think if the digital thermometer I had in there was accurate so last night I bought a standard glass thermoment (non mercury based) this thermometer is measuring up to 104 degrees. I then tried to candle the eggs and couldn't see well into them. Ive heard from other threads on this forum that you can't candle blue eggs till 14th day? Im thinking I should take some eggs out and break them to check progress and if they are developing then leave it as is, if not just discard them all and try again with white eggs for next try. My daughter and family thinks I shouldn't do this since I might break the few eggs that are developing.
