I have not had a whole lot a luck with this which I think is due to the lg but they are in a forced air hovabator to hatch. I'm still waiting on my 1588, I ordered over 4 weeks ago. First I ordered on ebay with double supply as a buy now and they never shipped my product said it would take 3-4 weeks. So after some rude communication on their part I cancelled and I ordered from cutler and they put me on back order too. They are due a shipment this week maybe I will have it by the time my next ones are suppose to hatch. Anyways they are at about 100 degrees, my humidity is a little high at 68% but I just took out the water rag I had and opened a vent. I will now sit on my hands and not open. I swear that is the hardest part.
