A couple of my ancona ducklings have their wings stuck out like penguins. They just hatched... and these last two seemed to take a little longer and had a rougher time. They were struggling a bit but after getting some vitamins and electrolytes seem to be moving just as good as the rest.... just look a little funny with the wings out. I had an older duckling get angel wing once.... is that what it is... or something else. Is there anything I can do.
