Hi this is my blue cochin rooster (LF) about 14 months old. About a month back he stated developing some breathing problems. I was hearing some crackling sounds when he breath. I was recommended to treat him with Levofloxacin and Prednisone for three days. I did that and his breathing problem was solved. Ok one more thing my roo was never very heavy or meaty. he was more on the lighter side on the weight scale, but he was crowing and crossing with females fine. About a month back he stated to loose weight as his chest bone was very prominent and no meat around it could be felt. He stopped crowing and crossing with females. Eating less. I tried some homeopathic medicine for this issue but he is becoming worst every day. Today i took some pictures of his head and droppings to share here so i can be advised properly. When i got him he was about 10 months old and head yellow beak and legs but now they are whitish. HIs comb dropped when he developed breathing problem and still you can see some spikes are not straight. I took some pictures (above) of his poop this morning. This is how his poop looked like (above) when i checked him about an hour ago. So i took him to his coop and gave him some bread soaked in milk. I asked my brother what was he using to treat him and he told me that he was giving him one table spoon Augmentin Syrup in one liter of water for last three days and will continue for four more days as his friend did the same when his hen stared to lose weight. So this is my story. Can some one help me with this, as i am unable to decide what to do. I dont want to loose this Roo. Any help will be appreciated. Here is picture of his vent which i forgot to post.
