incubating chickens

what kind of bator do you have? an what is your humidty at? and why are you just turning them twice aday?

 

Lots of possibilities...how good is it keeping that temperature and have you varified that temp with another thermometer? Define turning a little better...and what do you mean spraying...like with a spray bottle putting a mist on them?

How do you know they are fertile? Did you candle or what?

 

Chicken eggs do not need to be misted like duck eggs. Recommended hand turning is 3-5 times a day, but more often is ok.
Temps should be read with a reliable thermometer, and kept at 99.5 -100.5°F for forced air (with a fan) or about 102°F above the eggs for still air.
Humidity also should be read with a reliable hygrometer, and the range is usually around 45-55% for the first 18 days, then bumped to 65-75% for the last three days when you stop turning.

If they were due on the 31st, then they are likely not going to hatch. Candle them to see if you see any development or movement... if not, and you're curious, you can gently open them from the big end and see if there's anything going on in there.

 

Don't spray the eggs with water... use a sponge or folded paper towel to hold the water. It sounds like the humidity has been too high.

 

if you go to wal-mart you can get temp/ humidty guage for about $6.00 and then that will help you on your hatches.

 

Don't get discouraged it took me a couple of attemps to get it right. I do recommend that you check and see if an automatic turner could be added to your brand of incubator. The humidity is much easier to regulate if you don't have to open the bator several times a day to turn the eggs. Turners are not that expensive but manually turning will still work. Once you are successful you will be hooked on hatching chicks. Good luck and keep your chin up.
