I had that problem in one of my incubators, and I wanted to set more eggs than would fit, so I put a few in my other incubator. I'm really counting on at least a few in the original incubator being clear, because at lockdown, I'll need to move those few extra back in!
It's pretty easy to build a DIY incubator. I made one out of a small Styrofoam cooler we had in our basement and weren't using. You do need to be able to do a little simple wiring, and it is pretty important to have some kind of thermostat. I tried to regulate the heat of the lightbulbs without one for my first hatch, and I couldn't keep it from going all over the place. So I finally spent about $16 and bought an STC1000 from Amazon. It has made all the difference! (Two day shipping with Prime, since I was already in the middle of incubation, and I even fried the first one- don't wire it backwards! So I had to order again. )
You can use almost any kind of container as long as it is leak proof and not a fire hazard and you can figure out a way to attach all the components you will need and make vent holes. Fish tanks, plastic storage tubs, coolers. There are so many ideas here on BYC to copy.
