Where are we going wrong.

You really shouldn't see blood vessels day 18. They are practically full by that age. I suspect the temp was far too low resulting in delayed development.

Never use the temp/hygrometer unit that is incorporated into the incubator until you calibrate it with another device. I use oral thermometer because that is the most accurate device available for cheap. Incubators have vent holes in top, put the thermometer in that. The heating element turns on and off resulting in a high and low temp. Your aim is the average of that to be 99.5 F if incubator has turbo fan. If a still air then your aim in 101.5 to 102 F through the vent hole. An oral thermometer is used to calibrate the incubator temp read out.

Humidity is calibrated with a salt test. Whatever small dual device you purchased can be calibrated then in turn you'd have a working calibration for your incubator reading.

Try incubating at 30-35% RH then up it to 70+ RH last few days for hatch. Keep in mind humidity is relative to surface area of water not volume. If filling the smallest trough in incubator with water results in too much humidity then use a cup of right diameter that fits in incubator that results in 30-35%.

Salt test;

Materials- zip lock bag *quart size works, juice/milk or whatever cap filled with salt and small amount of water to saturate it, hygrometer.

Saturate the salt in cap, wet sand consistency. Put cap and hygrometer in ziplock bag, seal it up with little pillow of air inside and place on the counter overnight. A salt environment is 75% RH exactly at room temp. The difference between your hygrometer and 75 is the calibration #.

example- your reading is 83.
75-83= -8 You'd always subtract 8 from whatever your hygrometer reads for true Relative Humidity.

Aw that's great thanks. So there's one where I can still see vessels and the yolk. Should I be still turning that?

Anything past day 24 is a bust.

Try again with what you've learned here and calibrated incubator.

This is the only one that we can see moving tho. I can't grasp why this is only one underdeveloped, it was laid, kept, incubated all the same as the others. That's got me scratching my head
