My Runner Puddles hatched out about 7 ducklings maybe a few more to come... but when I first saw that they finally arrived which was this morning, one of them was laying away from the nest next to a broken egg which I assume to be it's own. I thought he was dead, so I left for a minute and came back to remove it, and I realized he was still alive. He could barely move and then my boyfriend said there must be something wrong with him because the momma kicked him out of her nest. So I put him in a shoe box with a towel and a lamp for warmth. And now about nine hours later he can lift his head and walk a little bit... What I want to know is should I put him back with his mother or is she going to try and kill it? Or if he still can't move as well as his other siblings should I leave him in the box alone until he is better and then later try and put him back with them? Also if I can put him back with her how do I go about doing so, because Puddles is extremely protective of her babies and has already tried attacking us for being in there? Sorry I've never had ducks hatch out babies before, I've only had ducklings delivered. And I want to try and let her raise them somewhat.
