Hi there.... I am in need of some advice. I have a 6 month old Pekin duck that came up lame about a week ago. We fist thought maybe a broken leg but after checking her legs which seemed fine we thought maybe egg bound. We soaked her in warm water and put her in a humid kennel over night, she layed the egg and has layed 2 more since. She still can not walk. She tries, but she falls over forward and has to use her bill to catch herself...she also falls backward on he heels of her feet and sideways and uses her wings to catch herself. We have no idea what is wrong with her, she is still quacking, bright eyed and eating and drinking. She can also swim just fine, but I have to go and help her out of the pond. Any suggestions or advice?
