I have a Cayuga that’s around 5 weeks old. I got him to be a friend for my loan Hatcher who is now just over 2 weeks old. One of the wings on the Cayuga is larger than the other. The bird is feathering walking eating and acting completely normal. I feed an 18% protein chick starter, lowest protein I can find in a starter with nutritional yeast mixed in for niacin. I give fresh greens every day such as turnip greens, dandelion, and peas. I have given some mealworms just to try and build a bit of a bond but that’s it. Is the wing a concern? This was the runt duckling when I picked it up but has been healthy and vigorous since it came in. Any ideas on what might be the cause or if this is not too abnormal would be greatly appreciated. Thanks in advance
