Friday one of the buff orps was just standing by the gate. would not eat when I threw out food. I picked her up and set her in front of the food and she just stood there. Found out that she could not see. I put her in the garage and a few hours later she could see. she will eat if u put food in front of her and she will drink as long as there is water in front of her. she will drink about a 1/4 a cup at a time. she is also spitting up water after drinking. she can stand but has to use her wings to move around and spends the day sitting and scooting around. her nose and eyes are clear. Her poop is normal. Not real interested in food but loving the water. I put a vitamin and mineral supplement in the water. She can not roost but she can "grasp" with her feet. She was perfectly fine the day before. Seems like she falls asleep every few minutes. She was out with the rest of my flock free ranging with chickens, goats, ducks, and my great pry.
