ALDI had theirs for 49c (or was it 59?) a dozen a few months back.  That was in the HEAT, when our girls slacked off so I actually thought about it.  Until I opened one and found eggs splatted with poo... okay that's a fluke opened another... poo AND feathers.  So I passed.  I don't scrub my eggs or anything, but if a commercial "looks matter" company can't be bothered, when likely their eggs roll down anyways, it makes me wonder just how nasty the cage is that they managed that much mess.  *shudder*  Not really any wonder so many people get sick is it?
