I have had bad luck hatching with an incubator before this, the temp was all over the place. My wife got me the Hova Bator 1588 for Christmas and it is holding temp perfectly. I was bad and forgot to check the humidity and it ran dry around week two and just before lock down. Hard to tell the amount of water with the egg turner in it. Yesterday was day 21 and I saw nothing moving, no piping and I just assumed I messed it up and that was that gave it 4 more days just in case. Today I went down and had 2 hatched and one breaking out! 3 of 12 eggs set is fine by me, I never did candle the eggs I just put them in. Once the 24 hour hold is up I will move them and pray my light going out and killing chicks curse is over. Twice last year once because of a GFI next was a light just went out no reason and then the power went out just to add to it.I will post some 24 hour pics of the fuzzy Jersey Giant/Ranger mix a funny mixed up color but still cute.
