I have been and spoken to the chickens today, who have assured me that they will redouble their efforts to eradicate all worms from their run....they do a pretty good job of it already.
I was thinking of topping the woodchip up rather than digging it out, but am a little worried about the potential for it to smell.
Good to know it can all be used - would it be too harsh to put around my newly planted raspberry canes? Or amI better to let it rot for a while?
