Hi! New to this forum because I haven't needed any help... but suddenly I have chicken issues. I have about 17 chicken, 16 guineas and 4 peafowl who all cohabitate at night and free range in the day. Recently I had a rooster who was sounding rattly..upper respiratory problemish. I treated him w/ baytril, took him to the vet, he had roundworms. Treated all the chickens and 2 of 4 peafowl, not the guineas, with oral ivermectin about 10 days ago. Was planning to repeat today but just saw a chicken with some foamyness around one eye... WHAT is going on? I have Di-methox, Wazine, diluted Ivermectin, and VetRx.... what should I do?? Appreciate any input!
