Hi! I have a 4yr old pekin duck that has had seizures since 16weeks old. We believe from trauma or vit deficiency. Lately her seizures are more frequent and she seems to be more sluggish then normal. I know she's older and everyday we have her with us is a good day. We give her brewers yeast and vit b complex injections. Just wondering if anyone has any suggestions to make her more comfortable? Thanks!
