Do you have a rooster? My rooster keeps my hens in check if they start to bully each other..he even protects my pet pigeon from the girls pickin on him.
I checked it around 11pm last night and it was 100, I just called my father and he told me when he left for work at 3am it was at 110 so he turned it down...then I just checked them at 8am and it was 115!! so I opened it, add more water now the incubator is at 95 with the humidity at 65%
