John had the same thought that I had.
I am not sure how long those chickens will last without onsite supervision.
Chickens need food, freshwater, and a predator-safe living environment.
What I did see that was good was a dump truck of mulch which is good and a cattle panel greenhouse to keep the mulch from blowing away.
Also good was to gather veggie scrap from local restaurants to add to the mulch.
I will add getting lots of coffee ground which might be easy and lots of bags of leaves if there are any still around now.
