since i introduced deep litter of hemicore and poultry powder(stanslon , may be spelt wrong) my test's have shown a very low cocci count against my previous routine of cleaning the floor daily or every other day,
i do however give my babies a canker tab at 25-30 days old, its something i have done for the last 5 years
and like terry posted i treat all new old birds for canker , cocci in a small shed 3 foot before they mix with any of mine
i use the same shed for any birds that go missing prior to putting themback in the main shed
