I have five hens but i only get like two a day. that and it just got warm enough for them to get in the laying mode agian. (the weather has been jacked up lately down here. 60 degrees one day, 30 the next and 80 the next.)
my first batch was my old bator (which i usually do good with) and i did not have a turner so i was trying to turn them and go to school until 9 two nights a week. so.....yeah............
this last one i had was in my brand spankin new bator (auto turner this time) and they were shipped eggs. only this time i was so worried about them hatching that i checked them nearly every day ( not really, but i did check them a lot) and the temp jumped around a lot. so there was some low and highs.
