a few of the flock raisers use chemical drums from sheep drenches and crop sprays feeders and waters are not cheap and cost a fortune to get a safe food dish chem free. they cut the drum open wash it out ten times let water sit in it for a whole week tip water out rinse and use again although this sounds pretty satisfing they are that prepeared to drink it thay washed it that many times. i use other containers that had no chem history is this a health risk worth sussing out and like tryes do they still old chem nasties info would be useful
Not sure if I'd use them. Depends on the chemical. But some plastics can almost absorb things. Filling them with water might be a risk.
