Since this is in the turkey section, I'm assuming the eggs in the incubator are turkey eggs and are due to hatch in another 8 days. That's pretty obvious but sometimes its good to state the obvious. The 8 days is an approximation. They could be early or late by a couple of days.
You do have some options. You can store them in 62 degrees Fahrenheit and turn them several times a day. It would help if you could keep the humidity up some where you are storing them. Eggs decrease in hatchability after about two weeks, but not that much if you store them in close-to-ideal conditions. Part of that depends on how you have been storing them. Of course, the longer they go the higher the risk. You will risk losing some hatchability but you still have a chance of most of the eggs hatching. It is not ideal, but not necessarily a total disaster. This is my second choice.
Another incubator is the ideal solution. If you make something, I suggest you just make a hatcher and when these eggs go into lockdown, lock them down in the hatcher. You can start out setting up your humidity where you want it for hatching and not have to worry about bumping it up when you put the eggs in lockdown. You don't have to worry about turning them either. And your incubator is not that hard to clean if you don't hatch in it.
At the very bottom of my list is adding them to the current incubator now and leave them in there during lockdown. What do you do during lockdown on the first eggs? Turn or not turn the new eggs? If you open the incubator to turn them, you risk shrink wrapping the hatching chicks. I've done that so I know it can happen, even if some others won't admit it is possible. Where do you set the humidity during lockdown? I think your odds of two successful hatches really drop if you try to do a staggered hatch in the same incubator.
