My ducklings arrived Thursday and one is walking with her head tucked down under her chest and off to the side and came out the box that way (she is active even with her weird neck). She eats and drinks okay and will move it to do that but seems to spend most time with it in the tucked under her chest position that kinda reminds me of a fetal position. I can lift her head and she will hold it up for a little time, and when my older guys come look in the brooder she holds it all the way up and will get on her tippy toes to make contact with them. But then she goes right back to her head under her chest. What could have caused this, can it be cured or will she grow out of it. And a really stupid thought can I make her a little ducky neck brace with something soft to help her and if I can does anyone have any suggestions on how best to do that. Could it be a vitamin or mineral deficiency (and what do I need to get her if it might be) although all the others are fine and she arrived with it this way. All babies are on unmedicated starter. Any advice would be most appreciated as we want to give her the best quality of life.
