For those who buy the Haybox Timothy Hay, do your piggies *only* eat the ears of the hay? The stalks are of no interest to them as they rummage through the hay rack to pick out those titbits. I don't know if it is worth buying another box (I find it expensive) even if the foraging does give them so much pleasure. I guess I should wait to see if the stalks are of more interest once every last ear of hay has been picked out from the original 2.5 kg! (Needless to say, they are given other hay -- the Pillow Wad meadow hay and the Haybox meadow hay, which is everywhere else.)
