I'm sure it will be fine but just a word of caution if you add the 16 to the incubator. If they are not very warm they will seriously lower the temps in the incubator. I stuck 6 in mine and the temps dropped by a degree for 12 hours. It took a full 24 hours to stabilize. I know the fluctuation was minor but I only added 6 eggs. It takes them a minimum of 12 hours to heat up if they haven't been preheated. I would suggest you maybe add half and the rest 12 hours later or even more staggered. You might ask why and that is a valid question, it might be negligible but the first time you set the eggs they all warm up at the same time. If you add eggs later the eggs are already in full swing of development and a drop of 1 degree for 12 hours should ideally be avoided. Depends how good your incubator can handle changes.
Just a heads up. Also think about when to stop turning and raising humidity - will the increased humidity affect the other eggs not in lockdown? Will you need to open the incubator to turn eggs during lockdown which most people avoid at all cost due to the sharp humidity changes caused when opening the incubator? The egg turner needs to be turned off and the remaining eggs still need to be turned yet during lockdown the incubator ideally should not be opened. Think about these challenges you will be facing.
