What am I doing wrong.

Ok so I just candles my eggs on their fourteenth day. About half of them havnt developed any since I checked them on the seventh day. I’ve kept my temp. At 99.5-100 degrees feghrenheit, and humidity is at around 40-50 percent. I use to keep it at around 30 percent till I read something about making it higher. I am using one of the styrofoam incubators from tractor supply that has the FFA stamp on it. These are eggs from my own birds. One had an obvious blood ring. The others are developing fine they are moving in the egg. What do y’all recommend?

They might be your problem. I have two incubators and neither (one from eBay one from local coop) readings are correct. Go to a store ASAP and purchase a good grade thermometer and hygrometer. You can calibrate them and check them for true readings.

Once you get them, make sure they’re correct. You can google “how to calibrate thermometer” “how to calibrate hygrometer”

The two methods attached work well. But try them several times to make triple sure your readings are the same each time. Before you start another batch in an incubator, test and calibrate them again.

There may be other, better ways but I don’t know them. I’m sure someone on here knows all the methods.

X10 on getting more thermometers to calibrate.
Walmart sells cheap fish tank ones.

I think your humidity is currently too high.
Get another humidity gauge and salt test it.

What thermometer and hygrometer are you using?

What thermometer and hygrometer are you using?

The one that is built into the incubator

My styrofoam bator has a good thermometer within .3 degrees, but it reads 40% humidity when it’s truly 70%. Not kidding. The one from eBay has a great hygrometer, but temperature is 2 degrees of more off. Reads higher than it really is. It currently says I’m at 39.9C and is truly at 99.7 degrees.

I spent roughly $25? Ish but I bought both online. If you need, I can find the link for checking them both. Unless someone else has the links handy for calibrating/checking.

About how much will it cost?

For a good hydro and thermo, not much. If you are planning on doing a lot more hatches i would recommend getting a higher quality bator.

Just so you can see how far off the cheaper incubators can be.
