That's very nice.... and refreshing, I might add....most folks don't like to hear straight talk.  Now, don't take my word on it only....go out and try it, apply it to your flocks and see if it's true wisdom and knowledge you can own.  You really can't own it until you've applied it and seen it worthy of passing along and using again down through the years.  If it works and stands the test of time, you can call it wisdom one day and let others know about it if they are in similar need.  If you've given it the proper and due diligence, just as it was described, and it doesn't work at all, no matter how many times you try it, then you can discard that one as not applicable to your flock/bird/life/circumstance and seek knowledge elsewhere.  That's the fun of learning about chickens...it never really ends, no matter how long you've been at it.
