Yes, it is important to give ACV for no longer than 3 days as it will interfere with the calcium uptake.I got the preventative work done...the ACV, the pepper and garlic. It rain again last night, so this work is going to go on for a long while. I cleaned the rooster ears infection with 3% hydrogen peroxide as I read from other cases. I am going to find details about antibiotic to give him as one of his ears is swollen. I read somewhere that in hot weather do not give chicken apple cider vinegar, we are in a humidly hot weather, so I stopped ACV this morning. A whole lot of work that is harder to do when it is raining, muddy and humid. I need a big massive jumbo giant coffee.
Did you check inside your sick roosters mouth for yellow/whitish plaque? Hopefully he will get better soon.
