I was needing some good anti peck spray for my polish. They just won't leave their heads alone. The issue isn't overcrowding. They have a big area. They don't bother anyone but the polish. Rooster Booster makes a spray. Just wondering what other people thought that had used it. Rooster Booster also makes a natural wormer. My chickens don't have worms that I noticed but thought maybe it may be a good idea to start on a good gental natural wormer just for preventive. I know a lot of people recommend DE, I'm still a bit uneasy about using it. I have read up on it and I don't like the dangers of silica on lung tissue. My kids spend time in the coop and I would hate to harm them. Thanks!
