One EE went almost completely blind. She can see a little, enough to get around. She gets her treats in her own bowl. Another EE went lame. Noticed her limping a bit a few years ago. Then one day, she couldn't walk very well. Her feet have curled up. She can get around. Keep her in a brooder in my basement, and she has a sand box with a child's tent over it, to take dust baths. In her dust bath tub, you would never know there is anything wrong with her. When the weather is nice, she goes outside in a fenced area to enjoy the grass and sunshine. The tent over the dust bath helps keep the dust from going everywhere! Never thought she'd live this long, though. She's a sweetie. When she's outside, she lets me know when she wants to go in to lay her egg. Yes, she's still laying! They're my pets.
