Dust extracted cardboard

not tried it but doubt that it can be as absorbent as hemcore.

Remember aubiose and hemcore are far more absorbant than shavings too  .
But yes please do a trial for us it would be interesting to know the outcome. I have seen cardboard bedding for horses before but it has never been that finely chopped and this stuff looks far better 

I agree.  matchstick like cardboard has got to be better than the squares (which is very heavy when soggy, and stinks to high heaven.

I would never use cardboard for my horses, but this looks interesting for chickens!

I'm not sure what the postage would be like on a 20kg bake - perhaps you could ask for a sample though?
