I have a flock of chicken. I have 8 chickens in good health. But my son noticed that one chicken had a bubble eye for 2 days. Today we have 2 more with the same problem. I did isolate the sick chicken but I dont know what medicine to give them. Should I take them to the vet? Does isolating them keep the other chicken from getting the disease? or I should treat the whole flock since I have also 14 baby chick. Please I need your advice ASAP.
