Banty hen has been quarantined from my flock for 5 weeks. all signs of cocci are gone and i have dusted her for red mites. She was never in my coop with the red mites. I have dusted her with DE and she is in a plastic cage with shavings treated wih DE. I checked her and I couldn't see any mites. I was wondering when it should be safe to introduce her.to my coop and flock. How soon can I redust? How long until it is safe to move into flock?
