How do you neutralise run smells?

[21hens-incharge]

So, before I had a chance to try any of these suggestions we found the real culprit of the smell. It was actually coming from a bucket of garden weeds and cuttings that had filled up with rainwater and been forgotten about down the side of the run. Emptying it was not a pleasant job, but at least I'm not blaming the poor chickens anymore. If I do experience this problem later down the line at least I know what to do now. Thanks.

Had me really wondering what on earth could make a bantams run smell. Good to know the problem is sorted out.
