Also what day should I be watching and around what time you think.?
Stop turning and put the eggs into lockdown on January 17th. A "day" is 24 hours of incubation, so yes you would count from 10am the 30th to 10am the 31st as a day. If your incubation temperatures were correct your chicks should hatch the 19-20th. Be watching out for pips/chicks peeping a day or so before that. Hope you have a great hatch!
