Yay for dryer weather. !! Well, if you’re feeding peas, you can put the liquid B complex with the peas, but really not too many peas because they need the nutrition from their feed . peas aren’t having all the things ducks needs. There are some highly experienced people on here that say no treats at all.. only the feed,.. and your poultry will be much healthier. Like @KikiI will do so. I am not sure this is the issue, however. One of my females, the oldest (I have three generations, she is from the second, the drake who is sick is the first,) is beginning to show similar symptoms (stumbling, slow gait.) I am feeding them more peas, hopefully that will help. We have had a lot of wet weather lately, which may have something to do with this, and we are expecting a stretch of drier weather for the next couple of weeks.
