I have hatched before and done OK, not excellent, but the last 3 hatches have been disastrous. In fact this one is the worst, not one hatched egg out of 30. This is day 22 and not even a pip or a sound or a rocking egg. Most had developed and thought they were good when I went on lockdown. My temps and humidity have been fine with my instruments and yes I have calibrated. I am at a complete confused state. So much money has been wasted in these 3 hatches. What I could have done with that money! Will still leave them for 3 more days and take a couple weeks break and try some of my eggs to see if I can figure what the problem sees to be. I have got to get this hatching thing down so I can continue my breeding next year. Thanks for letting me vent. Back to the grind building coops for breeding pens. Got 3 going at this time.
