I got my little ducklings Friday morning, and she seems to be the only one affected. Sometimes she appears totally normal, just a little wobbly. Then, periodically she has spells where she falls over and tends to roll over onto her back and flail her feet around. It's like she temporarily doesn't understand how to upright herself. When I help her up, she leans over to the right and stumbles around that way. She has to balance on the side of her beak as she is leaning. If I pick her up, she leans against my hand and acts like she cant hold herself upright. Her legs move just fine, and she is eating and drinking. I have seen her have 3 of these spells and it really bothers me because I don't know what is wrong. She is the same size as the others, and they are warm enough to somtimes move to the cooler side of the brooder to sleep . Earlier, she was just walking around and eating with the other girls and all of a sudden she was on her side and back rolling around. I have Vi-Tal in their water and they are eating unmedicated Kent Poultry food. Does anyboyknow what could be wrong with her? What can I do? I w ill appreciate any information you can give me.
