I have a new LG incubator. On Thanksgiving Day I put a Silkie egg - the last egg my white Silkie laid before one of my standard chickens killed her. I bawled uncontrollably when I buried her - I absolutely broke down. Then later the same afternoon I added 3 eggs from the refrigerator, but they hadn't been in there more than a couple of days or so. Then I added 2 Silkie eggs about an hour after my 2 remaining Silkie hens laid them. One was a buff Silkie and one was a black Silkie. The father is a buff Silkie and very beautiful. Then early the next morning I added a green EE egg and a very dark, reddish brown Welsummer egg...or maybe it came from my Cuckoo Maran, not sure. So, I have 8 eggs brewing and I hope most of them will hatch. I have had a couple of serious temperature fluctuations as the beginning, but not for long periods of time. Now they are at 100 degrees and actually fluctuate from 99 to about 100.5 or so depending on the temperature of the room. I try to keep the temp at exactly 99.5, but it ain't happening. The humidity ranges from 38 - 40% on the hygrometer I stuck down in the incubator. I very carefully hand-turn them after washing my hands with hot soapy water.
John Boy Walton carried an egg under his arm until it hatched. If my utilities go out, I'm going to figure out a way to keep them warm by building a fire in my Soapstone stove and putting the eggs near enough to keep them warm. If that doesn't work, I'll tape them to my stomach.
