So it turns out one of my girls REALLY likes ASFs, so I'm going to start a little colony. I'm planning on a 1.3 or 1.4 group. I've got the sterilite tubs as shown on the sticky, and have built the hardware cloth top and hopper (but reinforced stuctural and potential escape points with stainless steel mesh). Gravity watering system components from RBI are arriving tomorrow according to fedex along with exercise wheels (will attach to lid). I have washers to reinforce the opening for the water nozzle, and was planning on adding a drain hole (also reinforced) to the bottom (if that watering system leaks I'd rather have a wet floor than a tub of drowned animals). Giant bag of Mazuri is also on the way.

What am I forgetting? I know there's something. I've set up one tub for breeders, and two for grow outs, should I make a fourth?

Also I have not settled on a substrate yet. I noticed some people like the pelleted pine, is that the same size pellets as the ones used for horses? Or is it smaller? Do they prefer one type of bedding over another? I want them to be comfy and happy.

Thanks!
