I know I shouldn't have but I couldn't wait I was turning eggs last night on day 4 and the candling box was right beside the incubator. The temptation was too great! I candled 2 spitzhauben eggs and could clearly see veins! I candled 1 silkie egg whcih was one of only 4 with no obvious cracks from a shipment of 16. The others were frozen and cracked open. I really don't have any expectations for these 4 but you have to try I could only see what might be a bacterial ring forming. I will be out of town on days 7, 8, & 9. Should I candle everything the evening of day 6 and get rid of the suspects or take a chance and wait until day 10? I'm adding about 2 cups of water to the incubator every day and boiling a couple of gallons into the air in an electric frying pan in the room with the incubator and still dropping under 30% humidity in the incubator for part of every day. My neighbor said I could borrow a room humidifier which he hadn't used since his wife passed away. I brought it home but then discovered that it was a dehumidifier! I think I'll be ok on the chicken eggs but I have a few muscovy eggs in the bator too. I have an old Sears & Roebuck glavanized incubator set up in the basement I will move the muscovy eggs to as soon as I get the temp set. The room humidity is better in the basement and should be easier to keep the bator humidity up too.
