Never wormed mine either, don't understand te 'hype' on it, dad never did and his chickens were just fine for a life time....
Maybe because his chickens ate everything and something that they did eat worked.
Too much about worms and disease and all that. I wonder if what folks are doing or giving is causing more harm than good.
Some junk can shut down their kidneys if you over do it.
I hate to enter the worm thing again but I say if it ain't broke don't fix it. Don't mess with success.
I will ask this, why do my chickens peck at the paint on the coop? Is it boredom? They're in a run so not running around the yard.
