Do you seriously read what you have written and think YOU ARE NOT LEARNING ??????????????????Much the opposite really. The longer I've been in birds (going into my 20th year now) the more I realize the importance of having strong healthy genetics in a flock. I do agree that proper management practices are a tremendous benefit that one gains with experience (The best way to control disease other than breeding genetic weakness out of your flock? DRY living conditions). Plus, the added benefit of not medicating or vaccinating is you aren't putting that junk in your body when you eat meat or eggs from those birds. Same way it's far better to use natural methods to control parasites so you aren't using a chemical, I've actually known people to use frontline on their birds to keep them free from parasites, that toxic stuff ain't safe for dogs and it darn sure ain't safe for our birds, especially if we're eating their eggs or meat. Best way I've found, is with adult birds use cedar shavings (they aren't good if eaten, but an adult bird isn't going to accidentally eat shavings), use PVC for perches so bugs can't live in the wooden perch, and I'll make or buy a citronella and other essential oil spray that I use for flea control on dogs as well. Haven't had mites or lice for over 10 years on any bird I've owned, my new coops will follow these practices as well as having a dust bath area with DE mixed in with sand, a great idea I saw on here). I did have worms once in about 5 years ago that came with some birds imported from the midwest, but mixing diatomaceous earth in with the feed for a month or so took care of that problem (always used it for horse and cat and dog intestinal worms too)
The longer I live, the longer I raise poultry, the more I realize the old timers were right and did it the right way. Old school chicken medicine kit? A hatchet. I wish I had the strength to do that immediately, but alas I normally isolate, give some extra vitamin supplements and sometimes they surprise me by pulling out of it, which is great because that's a stronger bird.

Sounds to me like you are learning very well !
