I have heard my rooster kinda cough a little in the past but he was always full of zest, ate well, and seemed good for the most part. I just thought I would keep an eye on him and obviously keep him away from the other birds because he is new and I have only had him a few weeks. This morning I noticed he didn't crow like his usual self. He is in the house in a x-large doge kennel and when I went to check on him and feed he was just sitting there lethargic and did not want to eat I don't know what to do?? Could this be a upper resp inf that has now gotten worse there is no discharge from his nose or anything or could this be a heavy infestation of intestinal worms? I don't know what to do for him but he isn't lookin so hot this am at all and not eating scares me too. Any suggestions I am new in the chicken biz and have no clue what to give him or where to start??
