Confused Teachers

[Teacher906]

We decided to all hatch eggs in our classrooms this year. We have 3 incubators and got eggs from 3 farms. We split the eggs so that we all had the same amounts from each farm. We are absolutely at a loss for why 1 of us got chicks and the other 2 did not.

Day 21 was Wednesday...

My incubator was struggling to stay at a consistent temperature all along. My temp went up as high as 102 and down as low as 93 at one point. I would get it consistent for 2 days and then it would drop or increase fast. My incubator was opened multiple times with my classes to candle eggs. I figured I would not hatch any chicks this year! I have 10 that have hatched out of 41 eggs.

Mr. F's incubator had a consistent temperature all along. His humidity did drop low a few times, but for a short period of time. His incubator was only opened to add water and to candle one time. He had zero chicks!

Mr. N had a brand new incubator that was digital. His humidity and temp were perfect all along. After day 18 he had trouble getting his humidity up, but by day 19 it was up to 70's. His incubator was barely opened at all. He had zero chicks!

Everyone sure is puzzled as to why this has happened! We felt that, if anything, it should have been my chicks that did not hatch. Any thoughts?

Did Mr N and F candle their eggs for growth? is it possible their eggs weren't fertile?

Were the thermometers and hygormeters sp. calibrated to assure that they were reading correctly. Given that egg sources were the same for all three incubators, I would guess that temperature and humidity sensors were reading incorrectly.

Mr. F's was accurate. We switched his and mine to check that out earlier when we discovered mine was slightly off.

Mr. F did candle his and had many that were fertilized and were showing growth. Mr. N did not candle his. all 3 of us had the same number of eggs from each farm. In fact Mr. F brought eggs from his own chickens and none of his hatched in my incubator while the other 2 farms had 5 and 5. We are questioning weather any of his are fertilized, but are going to keep them in the incubators this weekend.

When you say that incubator was barely opened, were the eggs being turned? Was there an automatic turner?

None fertil eggs??

Yes, all 3 had auto turners...

None fertil eggs??

We can check next week, but there has to be some fertilized eggs because we did have 10 hatch, 5 from one farm and 5 from another. We split the eggs evenly from each farm.

What was the humidity throughout incubation for each group? Did each group have a calibrated hygrometer?
