Madagascar Hissing Cockroaches Doing Good

I put my roaches in a bit bigger of a container. A 66 qt Rubbermaid tote to be exact. They are really starting to take off. It's rare that I don't spot at least one or two pregnant females when I look in. I'm super excited because I only started with three! The only thing I wish I could do is find someone who wouldn't mind swapping out about half of mine for half theirs. Just to keep the inbreeding down some. Especially since all mine came from only three roaches. Not much diversity and I think the three were siblings too. I'm glad they're taking off. Do any of you think I could have problems down the road with such a small gene pool?

Inbreeding is more of a mammal thing from what I've read about it. It doesn't even necessarily pertain all that much in reptiles.
Insects I don't suppose would be any concern.

That's good. I'd hate to see problems with them finally taking off.
