We have a cattle collecting yard that we'd like to use for sheep occasionally. Problem being, for scraping out, it has a slated slurry tank running across the middle of it.

Needs to retain a degree of load bearing so replacing the slats with expanded metal sections isn't an option. Possibly could put the expanded metal directly on top of the slats but it won't be used that often so a bit expensive and might not really work anyhow?

Anybody got any ingenious ideas that they use for sheep on slatted cattle areas? I'd be thinking it's probably not an uncommon problem.
