Ahh isn't it fun. My hubby left out a massive piece of polystyrene without my knowledge last night. When I got up this morning (he lets them out early) they had basically consumed the entire thing. Needless to say I am now worried to death and watching everyone like a hawk. Gahhhh!!!
It never seems to hurt them. I am not sure what the fascination with it is to them though. Miracle my isa brown rescue hen will get into it in hubbys shed if she can find a bit anywhere. Never hurt her so far.
