I am a new member to the forum but have been reading these boards for years. I decided to come out of lurk mode to ask a question on something I have had problems with over the years...."going light". I mostly keep Canaries and have seen this happen a number of times. It is usually an adult bird that over time loses muscle mass in the chest and then eventually dies. I have one now that this is happening to. The sternum is sharp, but the bird actually has fat on him. He eats and drinks, but is puffed and not singing. Nothing I have ever tried in the past has ever rectified this situation. I have read that the cause could be a fungus or bacterium, or even dietary deficiencies, but I am at a loss as to the seemingly random nature of the birds that are afflicted. Does anybody have any insight as to the cause of this, or what a viable treatment might be?
Thank you in advance for any insight....
