My duckling has a funny wide stance and if she runs too fast she falls on her face. Her stance is really wide. I have other ducks and a great guard French Toulouse. None of them had issues. Feed - Purina Flock Raiser Supplement - Nutri-Drench Poultry Drench in water Started Niacin powder in Water 3 days ago. Has anyone seen this before? She eats and drinks great. Just sits a lot and walks/runs funny. She is by far growing faster and bigger than any of my other girls. It's strange. This isn't my first rodeo with ducklings just my first with this issue.
