Hey Everyone. I hope I can get some help. I just chunked batch 2 of duck eggs (Rouens) for never developing. On spot checks at least half my eggs have been fertile. This batch was of 20 eggs. I cracked every single one and 11/20 were fertile with zero development on day 9. Forced air incubator. 99.5-100 temp as confirmed by 2 digital and one glass, humidity 55-60% and and Auto egg turner. I have no idea what to think about this. I went ahead and put chicken eggs in to see what would happen. Could it be the incubator even with 3 separate readings? I just don't feel like that could even be possible. What are the chances I have a drake that has bad DNA? The eggs are from 6 hens. All turn 1 next week Thanks for any input Christine.
