So I've been breeding ASFs for almost a year and a half and as my colonies have grown I have made some observations about their behavior.
Most notably... their chewing habits. When I only had 3-4 colonies, the chewing was never too bad. I have chew blocks, cardboard and paper for them to chew on but for certain groups, that just isn't enough.
What I have found to be the most helpful item to deter chewing is the running wheel. Here are some comparison shots. Sunday I cleaned out all the tubs and left my other 3 wheels to soak overnight (they were nasty). I left this pair for ONE NIGHT without a wheel and this is what I wake up to.
They chewed through nearly all their food in ONE NIGHT.
Here is what the group next door looked like after one night.
Conclusion: the wheel helps IMMENSELY.
