I talked to the Hatchery and she said she had the same issue I had in my incubators. They our a pain. She said to save and regroup and invest in a descent incubators that more reliable. Brisela one not sure if the spelling is right. She said they give better results. Then styrofoam or sensitive incubators. She said her eggs would all die within two weeks due to spikes and changes in them.in her styrofoam one. It makes to many hot and cold spots.
Interesting because I have been using Styrofoam for about 6 years, I LOVE MY HOVA BATOR. I have my eggs in my Homemade bator right now and things are going great, I have four call ducks due tomorrow and a Goose this friday.
I have hatched out many many many eggs.
