Ok I will try to make this long story short,but I have a little billy I got when he was a month old. He was doing great at the beginning and he just wouldn't grow or gain weight! I have tried everything to put weight on him. He has never been vaccinated, and it is not worms. For some reason he has no muscle! He looks very skinny but still eats fine! But NOW! he is weak in his hind legs but once hes up he is ok. So confused of what this could be? Can it be wasting disease? Please help! Think he may not make it much longer! Like I said we have tried minerals, calf mana, nutri-drench and other stuff but nothing helps him. Thanks!
