I have had her on niacin and baby poly drops w/o iron since she hatched. She loves to swim but I have to carry her to and from the pool. She enjoys taking in some sun but at best she can take 10-12 steps then she really struggles. Legs and feet look normal. I don't know what else to do for her. Can anyone offer any help or suggestions? She is a lonely duck because I can''t put her with the other three because the gander is too rough for her and her leg..Besides she could never keep up with them.
