Can anyone recommend a good bulking agent?

[General Armitage]

Hi there,

I need some fine organic wood chip to replace the bulking agent which came with my bin and I have now finished.

I previously bought organic wood chip from a garden centre. It worked ok but was too large.

Can anyone recommend a good product? I don't need massive amounts - standard bags are ideal. Links appreciated.

Thanks!

Chipped wood is sold at a fairly reasonable price by companies involved in supplying material for lining the bases of chicken coops
