3 weeks ago I hatched 8 Ducklings. One of them, a Black Swedish, has a deformed leg, totally useless. He has also not been growing as quickly as the others. I have him in his own enclosure in the house. He is very attached to me. Any ideas of what to expect with him? I realize he will always be an inside duck so I will need to start diapering him. He hops around pretty good but not for very long. He uses a stuffed animal to rest on so his chest and belly are not always on the ground. His little body is becoming somewhat deformed due to the muscles developing on one side and not the other. I probably should have culled him once I saw his leg but I just did not have the heart to do it. Has anyone experienced anything like this before?
