We JUST did this same thing to stagger our hatches out. We JUUUST made our DIY bator with an IncuKit. AWESOME! we love it, and it is soooo easy. we also will just keep the LG
Now you're thinking. I have an LG and a homemade incubator. My homemade is created from a plastic cooler. Better to keep the LG in one piece and build the new one from other peices. Most people like having 2 incubators. One as a hatcher, one as an incubator.
Lots of info here on BYC to build an incubator; read lots of ideas to decide what design you want.
