Superworm crowding?

[TwinkleToes19]

I've noticed after cleaning their enclosure my superworms have been crowding in the corners? Should I be worried or this just normal behavior? I use wheat bran bedding (1 inch atm) and feed them carrots every couple of days. They're are roughly 30 worms in the container. The temperature is also 70 degrees F, so I don't think they're overheating. It's also going to rain soon so I'm wondering if it's because of that.

Could be they sense the coming rain. More likely that they just wander around and get caught up in the corners. If it was one corner close to a running electronic device or something I'd say it was warmth/heat but I think the weather sounds more plausible given what you said.
