Ideas for furnishing run?

I had a branch in my run and was warned off on another forum as they said it was a host for red mite to get into the run.  Has anyone any comment on this as you can imagine it really limits what we can put in for them to play on if we can't bring wood in from the garden.

Seems a bit over the top to me, (no offence intended!) and I don't really know that much about chickens tbh but loads of people put branches/tree trunks etc in them.

Was it just one person on the other forum or the general consensus of opinion from members there? Wasn't the omlet forum was it?  Just that with them being plastic houses the owners do seem a bit more concerned about contamination I think, maybe?

If it was just one big branch you had and were really worried couldn't you just dust it occasionally if you felt it necessary?

I asked another question earlier about do people dust their runs for red-mite, only one reply so far but it was my (Novice) understanding that the mites only come out to feed at night so I'd have thought it'd be pretty pointless hiding in places where there are no chickens at night!

I haven't put it in yet, they've only been here 24 hours and I don't want to spook them, but I have an old plastic dustbin without a bottom (I cut it off and used it as a raised bed for root veg) that I think they may enjoy.
