The best method for the dung beetles productivity and keeping them out of the way…

When building your Dino garage make a lower level (only one wall high) underneath your Dino pen and use it as a dung beetle pen, (I keep my dodos down there with them too)

This way when you sent them to wandering they will have access to all the dino poo and keep your pen clean but not get in the way. No escaping. (make sure to close the door when going in and out)

Only level up weight. And when they fill up with fertilizer, either use it or drop it all after collecting the oil. The oil production slows down when they are holding too much fertilizer.

I have 4 beetles under my Dino pen and every day I’m getting about 600+ oil
