Would that have to be done at the vet office exclusively? I've checked around feed stores and they don't know what to give me for that accept the antibiotics. I want to prevent the spread of it, not so much just cover it up or give them more internal damage as you were saying. Any suggestions would be greatly suggested. I know their is a lot of controversy on giving the chickens anything from the view of organic famers, but I would like to prevent the disease as much as possible and effectively. I do the cleaning of the feeders regularly and what I feel is the appropriate way, but you know sometimes they get a sip of some bad water somewhere or something hanging around the yard and the next thing you know they looking like they gonna croak over. Next thing you know you have to segregate the flock and slow down the eggs from reaching the refrigerator due to antibiotics when those natural remedies no longer work.
