Fat Blocks

I've had mixed success with fat blocks and at the moment they don't get eaten very quickly at all.  I'm not sure if I've bought a duff brand - I will keep experimenting and update if I find a more popular variety.  As I don't like leaving very old food out for the birds I replace them every week or two, depending on the weather. Otherwise they start going mouldy, especially in the wet.

One trick I have adopted to avoid waste, is to cut the blocks in two and only put half out at any one time.
