Wow! Not often the poop is so full of round worms there is no need for a fecal float test. The only thing lacking is the flashing lights and air raid siren.
Watch the chickens carefully following the worming. Heavy loads can cause issues from crop slow down due to obstruction from too many worms to be absorbed and digested by the intestines to shock. Be prepared to treat a crop issue if the crop shows signs of not emptying overnight. But watch especially for signs of shock - lethargy, imbalance, leg weakness, overall drunk-like behavior. Treat with electrolytes immediately if you see these symptoms. Shock can kill quickly.
