Need some help here. I have a 5 yr old rooster. He is w 30 hens and 1 other rooster who is the dominant rooster. I have noticed over the past couple of months that Kenny - (the rooster I am concerned about) seems to be thin and weak. Brought him over to the house, thought I would give him an opportunity to build up his strength ( thought he was not getting enough to eat w other rooster). He seems good during the day, eating well however he does seem so sneeze often and at night when I have him in the kennel box and when he is lying down in the house, he has open mouth breathing. Any suggestions??? I have read that gape worm can be treated w Valbazine. 1/2 cc - but my question is how long to you treat for? And not sure this is what I am dealing with - help? Oh and also when he is standing - there is no open mouth breathing. He is eating, drinking and seem alert, however I have noticed that he seems to sneeze a lot during the day. My thoughts were to bring him over to the house to join 4 hens here, let him be the rooster here but I am concerned to put him w the other 4 hens. The rest of the flock that he was with - 30+ hens and rooster are all in good health-no others are showing any kind of symptoms. I did not realize that he was in this kind of shape. There was nothing obvious until I brought him to the house to observe. It seems that he is struggling and I would appreciate any input or suggestions to help him and me out. I would like to keep him here at the house w the 4 hens - no competition and he would be the dominate male, but I don't want to bring anything in to my hens. Please help and I welcome suggestions. Thank you!
