I wonder how long it will be anti bacterial if they build resistance?
And I wonder how long before the bacteria from your arm crawl back to your hands?
I think building some resistance is key. I bring in a clump from the pasture as early as possible for chicks at least by a week. My broody hatched babies are out there from day 1. Chicken poo happens. I think proper management is
necessary! It keeps things in balance. Things like mites, lice, intestinal worm, coccidia. Anything allowed to be out of control is never a good thing.
I use a droppings board in my coop that gets cleaned once per week, sometimes less depending on the weather pattern. Wet poo smells terrible and gets things growing in it. Dry poo ain't delightful but it also isn't loaded with amonia. So it has a longer shelf life in summer than winter. It catches all night time dropping which is when the shooks spend their most amount of time pooing in there. I keep food and water out of my coop to reduce indoor waste. I change out nests that had broody's in them pretty good and refresh others as needed. I do kind of like shavings in the lay box better than hay. If it's gross it goes to a garden bucket, but if it's just old I toss it onto the coop floor which is a base of washed river sand (a little dustier than I would like). And as suggested might go to the garden yearly from the coop floor. I do have a lower roost which gets used on rainy days and when integrating younger or lower birds.
Outside the covered portion of the run has a forest floor type feel. Built up with dry grass, leaves and that type of stuff. Bare dirt invites disease. With a nice layer of not exactly compost (but ya compost), it's dry enough that it usually hides things before I see it. Any large poos sitting on top get picked up at least daily. I am fortunate to spend more time than needed with my birds! So I often walk at least the heavier used portions and the animal highways on my property at least twice per day. I realized that every time my neighbors drive by I'm standing out there with a poop scooper. What must they think of me.

No I know, I do more than I think I do. For me, I'm just walking around kicking things over and and be followed by a parade of ladies with veracious appetites both for bugs and the enrichment.
No way do I kid myself into believing that I find every chicken poo. Nor do I think that there wasn't poo juice left behind that already soaked into the ground.
But you better believe I'm gonna do my part to insure that things don't get out of whack. All situation will be unique. I have never bleached a pet bowl. If it grows green stuff from the sun or gets dirt stuck on, or even a poo floating...I simply use one of those dish scrubber sticks to scrub and then rinse with plain water.
I bleach my counter if I'm gonna roll dough or something. But if I'm using a cutting board, nah. I don't know we eat thing that were left out all night all the time.

Like pizza, spaghetti, rice. Sometimes that depends on the season.
Ugh, my floors are so gross. But I'm not eating off of them. If I had a baby crawling around down there, I would make efforts to keep it clear. But then again, I've seen them pick a shoe up and put it straight in their mouths.

They were none the worse for wear. But... I'm not about to try it.
Those with healthy immune system will have higher tolerance in general. So what work for one may not work for another. But standard soap has been shown as effective as anti bacterial. Why add more anti biotics (is that the same as anti bacterial?) into my families life and help to create more super strains of staph and other resistant things?
