If one's birds are laying 5-7 eggs a week, they'll lay 80% or more by 10 AM. The rest will come periodically throughout the day. If they aren't laying that consistently, perhaps more will come in the morning.
It takes 26 hours to build an egg and ovulation usually doesn't happen for a while after the egg is laid so they'll be a bit later every day until they skip a day because they won't lay at night. All the rest of the eggs in the assembly line will come first thing in the morning for up to 12 days till they start coming later in the day. Time of year will make a difference but this is why so many people think all their eggs are laid in the morning, It's because most are.
