Beware the self-proclaimed Chicken Gurus! Do not blindly follow anyone claiming to be infallible or making claims of a life of 100% trouble-free birds.
Quite a few "gurus" have developed a cult following, especially in the so-called natural or holistic chicken management arena, but many are giving plain old bad advice along with incorrect information. Some have basically declared their methods perfect, bolstered by their wide-eyed minions, touting their management style as the only way to deal with your flock.
If their advice does not produce the promised results for others, the guru rarely blames himself/herself, but asserts that the other person was at fault somehow. They imply that a *good* flock keeper will do it their way and if they don't, or it does not work as expected, then that person is incompetent. If the unsatisfied follower then seeks alternate, and possibly more traditional answers, he/she may be drummed out of the Minions Club.
An example of this misinformation involves herbs curing respiratory disease: herbals cannot cure mycoplasmosis, Coryza and other respiratory diseases once caught. Those diseases leave birds carriers even when symptoms have abated. The claims of cure-alls are false, but they persist. Please do your research!
