It is true, it is really convenient to transport, for sure!
So I spoke too soon on the nets (and of course, I have already ordered another set, yay!). Today he seemed to really be having trouble getting enough out. It's weird because he's been eating fine out of them for three weeks, not sure if it's just that he's frustrated now that the nights are colder, maybe he isn't able to get enough more out to compensate. He's really biting and pawing at the net and has started to do some damage, so since it's going to be cold the next couple of nights I just moved it into a single 3/4" net. He'll probably stuff himself silly but at least he won't be cold!
Next I'm going to try the tub setups again but with the topper clipped back to the bucket again a few inches down from the top to reduce the amount of slack in the net so he can't pull it over the side and shake bunches out that way. Maybe this is best for winter and the doubled nets are best for summer, we'll see. Of course it will be a situation where I'll need ALL THE THINGS.
