Hello all, I am brand new to ducks and have a question for the group. I have ten 5 week old muscovies who are all growing like weeds. We got them when they were 3 days old, fed them chick starter with brewers yeast supplemented and gave kale for treats. We had one we named gimpers right away because he was more lopsided and a little more bowlegged than the rest. He has been this way ever since the day we got him. As he grew he was slower than the rest and can't keep up while running through the yard. He also is very unstable (it seems like his right leg is weaker) and flips on his back often. Most of the time he can right himself but more than a few times I need to flip him back over. When in the brooder laying he would also kick his left leg out to the side while keeping his right leg tucked. This week I added sav-a-chick electrolytes and probiotics to their water hoping this would help perk him up and strengthen his legs. His legs do seems to be stronger than they were and he is keeping both legs beneath him when he lays down. He has always eaten, drank, and pooped just fine. Now today he had what appeared to be a seizure. The stood straight up (looked like a runner duck!) with his neck stretched and was stomping his feet up and down. Did this for about 5 minutes then kind of collapsed to the ground looking exhausted and disoriented. This passed after about another 5 minutes and now he seems back to his goofy self. Has anyone ever experienced this before??? Any help is appreciated! thank you!
