First time breeding gongys

[Savechanges]

I have a medium sized colony of gongys

( 5 males 9 females ) not all are adults yet 

I have breed one pair so far. The female layed an ootheca 2 days later. I have other female ready to breed and lay oothecas I am wondering if I can wait for 3-5 ooths to be laid by multiple females until I start to incubate them or do I have to start incubating them ASAP as they are laid?

If you're keeping the females warm as they should, you can just leave the ooths where they were deposited for ~4 weeks. 

The idea of an incubator never really sparked my interest. I don't think they actually make the hatch rates any better. Nature fluctuates and so should the terrarium.
