This is day 23 of incubation. Just a barn yard mix of eggs. There are in an older 'Little Giant' with egg turner. Figured things just didn't work out. So I took one out and dropped on a rock to see how rotten it was. To my surprise it was still alive and developing. But is was a long ways from hatching. Guess I'll keep waiting. How long should I give them? On a side note I have also bought a newer 'Little Giant'. This one has the digital read out and all. Got goose eggs in it. everything went good for three weeks. Then one cold morning I went the check them and the temperate was 121 degrees. Cooled it back down and has worked fine since. Course I know the eggs are dead. I haven't messed with them. They were to be ready in about six more days. Taking up a new collection from my geese now to replace them. I was at the store I bought it from yesterday. I told the lady they cooked my goose. Picture is about 30 minutes after I murdered it.
