I bought a set of a huge galvanized feeder and waterer and heated base from a garage sale for $15. Mostly, I just wanted the heated base because they’re like $60 at the farm store here. But I have soaked the feeder and waterer in bleach and scrubbed with soap and water. Is is safe to use for my flock? The previous owner hadn’t had chickens for years and they’ve been in storage she says. Bio security - wise i would hate to use them with the risk of transmitting something to my flock. I wouldn’t be too upset if someone recommended not using them, i would just toss them. Like I said I really just wanted the heated base. Thoughts?
