I had some similar quality manure from the same guy last year which I did dig into the containers and it did no harm. Except the mix I was using last year was so unsuitable in the first place, anything to lighten it up was a good thing.
And of course digging in 'a bit' is not the same as mixing it 50 50 with peat... I think you guys are right. Sigh.....
I should probably use the manure to build a new garlic bed for the fall.
Sooo... guess I gotta go pay up and haul the compost too.
Thank you for stopping me from my crazed lazy plan.
