ok, so I lost our Black baby duckling a few days ago. He was not growing and I suspected failure to thrive. Now a few days later his buddy is not doing so good!!! Bob (the duckling now) has been growing fine and getting little feathers coming in, but is not walking much anymore. The first two days were nerve racking, he would cry and cry for his friend, and everyone is out of ducklings at the moment so he will have to be by himself for awhile. What scares me is that he is starting to show the same symptoms Boss (the black duckling) had! except he is growing and gaining weight. It seems his legs re getting weak and his legs are not bulking up though! I am feeding regular chick starter. I checked to see if it was non-medicated but does not say on the bag. I am going to call the feed store in the morning, but they were the ones I bought the ducklings from and said to feed them the same feed as the chicks! When I was younger I remember my family feeding all our ducks chicken scratch! And they grew up fat and healthy. Should I use this instead? Any advice would be appreciated thanks!
