My chickens think water is the devil they run screaming from the hose. if i gave them a tub they would ask why they were being punished. I squirt em with the hose if they get in the garden they RUN AWAY.
My chickens watch the tomatoes grow when they turn pink they sneak in to the garden to eat them off the vine. They risk the wrath of Mom and the hose for a tomato.
I have never had styrofoam around my birds. That crap is bad. But I did give them cat treats they love them. With a picky eater I have had lots of cat food the cat would not eat and the chickens love it. Now I read it's bad, scary , glad I didn't poison them.
