sorry if I am starting repeat threads but I am looking for anyone who can respond 24 in incubator

post #1 of 9

What should I do??  My daughter's teacher hatched two eggs in a classroom incubator last year.  We took them home...50/50, got one hen and one rooster.  Trying to do full life cycle here...she had the incubator going again with eggs the school get and I put 7 of our eggs in to see what happened.  One went bad.  Two hatched on Friday (they are in the brooder).  My 4 are the only ones left.  Today is day 24.  We had agreed to wait until today (Monday) before pulling the plug.  Before I let her I wanted to do the float test just to make sure.  3 didn't pass but one is bobbing and rocking.  She doesn't have a thermometer or way to read humidity in the incubator.  I put a small thermometer in and it appears to be about 97 degrees (I don't even know how to turn it up).  I am worrying that it's not humid enough and was going to put a wet towel in.  I am scared about the whole "helping" thing.  I was over the moon that I even got two.  I just don't want to abort the one that is rocking in the water!  I don't want to be too much of a pain to the teacher since she was nice enough to let "crash" her incubator in the first place.


Any help would be appreciated.  Thank you!!

Let it incubate another day or two. 


Before the teacher does this again, inform her about temperature and humidity needed to successfully hatch eggs.

Thank you for responding.  We are leaving it in there for a couple of days.  I put a wet wash cloth in there with it...I wasn't sure if I should.  She does this every year but has an older styrofoam incubator and she isn't very technical about it (whatever happens, happens).  She always has some hatch.  I only did the float test to check because I didn't want to abort one of my living eggs.  I am going to look to see if I can buy her a device that shows the humidity inside her incubator.  Do you know if they make such a thing?  I had toyed with the idea of buying my own to put these eggs in but we are only doing it this one time so it would have been a large expense for a first and last trial.

I use the Incutherm thermometer/hygrometer.


I have both the regular and the remote.  I like the remote since I can put the sensor closer to the eggs.  Whatever you get, you need to check the accuracy of it before using it.  One of mine is off by 5%.

That's perfect...reasonable price!  How do you check the accuracy of the humidity part?

I filled a soft drink bottle cap with table salt and a little water. You want it moist but not salt water wet.  I put the cap and the entire hygrometer in a plastic tub with an air tight seal lid. Some people use zip lock bags, but I had better results with the tub.

Wait for 8 hours or so and check the humidity reading. It should be 75%.  What ever the difference is, mark it on the unit with a marker. Like 5% low or 5% high. That way you'll always know what to add or subtract.


Another tip for you to offer the teacher, make a spreadsheet with columns for incubation day (1, 2, 3, etc.), date, morning temp and humidity, afternoon temp and humidity, evening temp and humidity and water added.  I use this to keep track of trends during my hatch. She could have students do the record keeping and come up with some creative assignments to go along with it.

Okay...humidity-knowledge challenged over does the salt play into it?  Just curious.  I googled a bunch amount humidity but  didn't follow...I am not very scientific.  I like the chart idea.  It's amazing how many lessons one can create from this experience!


btw...nothing happening still.  Would there be a point (like tomorrow) where I should water test again?  And if it still moves, what to do?

when salt and water (NaCl and H2O), are in a saturated solution at equilibrium, the resultant humidity is 75%. 


I take that today is day 26 from your initial post. You could float test it, but I don't think that going any longer will help. Someone else may have a different opinion.

There's a crack and peeping!!  I really hope to meet him tomorrow (thinking he is a boy...did the wing test on the other two and they might be girls...I think temperature in the incubator is low).  Amazing!  I hope he doesn't need help out because I don't feel confident enough to handle that.


Thanks so much for all the info about the humidity...very helpful.  This entire experience is incredible and vey educational!
