I bought these to feed and water my chickens. When they arrived the smell was so awful it went straight into the box. Those rubber tubs have such a toxic smell. I can't feed my chickens this as I feed everything organic. Even if I wasn't feeding them organic, I wouldn't use them. I washed them with hot soapy water and scrubbed them like hell. You still stink. I left them outside and wiped them down again and they still stink. Don't waste money. They are not usable. Very disappointed.
