My beautiful silkie cockeral was fine when I brought him home 4 months ago. Two weeks ago I noticed he was struggling to walk. Thinking he might have injured his foot or leg I confined him to a cage so he could rest. After a week of quiet confinement, I took him out and set him on the grass. His mobility appears to be more limited. I checked his feet and they look fine (except for one questionable toe). He's eating and drinking fine and is talkative. I continue to cage him because I feel he is too vulnerable. In the morning I put him out with his 2 companions in a protected pen for socializing and fresh air and sunshine. Each day though he seems to move less. He'll stay for hours in one spot. When I pick him up and then put him down he is unable to stand. He topples forward and struggles to get his legs under him. Anyone have any ideas????
