I have heard so many differing opinions about the tempratures in the still air Hovabator. I am not an old hand at incubating, but I have hatched two or three times last year. But...I was using a toaster oven and it worked fantastic on 100 degrees and a full pan of water. Now....I am a bit confused about the hovabators correct temp. I have heard anywhere from 99 to 103. So which is it? And will they fry if it is 102 or 103 for any certain length of time? Next question: During this last batch, my power went out for almost 18 hours. So I put the eggs under the hen outside until the power came back on. Would this have caused harm to the embryos? Because on the 18th day I had several that had a broken air sack I believe. (The egg when turned shows the air cell sort of free floating?). So I lost all those and they were silkie eggs. Been trying to get my own brood myself. The rest of the Silkies are still in the incubator. Due to hatch today and/or tomorrow (unless the power situation delayed thehatch I now ordered more silky eggs, so what ar e th repercssions (if any)of having thepower goe up while the incuabor is keeping.Ishould say hatching.Tehe! I have no pips as yet. Please feel free to add any and all comments and ideas. If they dont hatch tonight or tomorrow,what should I do? Thanks guys/gals.Tehe!
