I collected some eggs for 4 days and put em in incubator. So does this mean the eggs are on day 4 or will they be considered to be on day 1? (I don't have incubator, asking for someone else) Thanks in advance.
Day 1 is at the end of the first day you start incubation. So if you set the eggs at 7 am, all day, this is day one. Tomorrow at 7 am, will start day 2, and so on.
