Most of my hens took to the Astroturf straight away, but for a couple of hens, I needed to put a little of the old nest box bedding over the top for the first day or two. Just a shake was needed to remove the old bedding and a little dirt. It is marvelous, as I don't have to keep replacing bedding and that is time saving. Have not had to wash it yet but it looks as though hosing will be all that's needed. Eggs are cleaner too.
