My farm worker just told me the chickens are coughing. Like half of them. We were in the middle of trying to sell them. If we treat them... I guess we have to stop selling right??? If so, how long would we need to wait for? People come to our chicken house to get chicken. I found out he was letting the people inside the house... even though it was not the main area where the chickens are. Some chickens go into that area. Now they are sick. Any advice about when they will be safe to sell?
