I have a rescue Silver Laced Wynadotte who is blind in one eye. She is now about eight years old. We adopted her when she was barely one. Over the past week I've noticed she was not very active, and then saw her stand up, take two steps and then sit down. Alarmed I put a bowl of water in front of her and she drank. Then a bowl of food and she ate. Normally I have tube feeders and waterers in their run, which is quite large, so I doubt she will be able to access those. I posted pics of her feet and legs. Any advice? Thanks
