my duck is hurt

This morning my ducks I think we trampled by my dog not sure she's usually really good with them well I'll get to the point there necks were floopy I raised both of there next one slept and woke up and started eating n is doing find the other one is still not but he's in a blanket and is now getting some sleep if his neck was broken was wondering if he'd still be alive I don't think so but wasn't sure cause the other ones neck was limp now he's moving it and is normal but this one hasn't even tried for that much movement but talks a little but tounge not moving what should I do cause if he's dieing I don't want him to be in pain but I also don't want to keep him alive just because I think he might live that's cruel both ways is I love him so much

 

Thank you for your feedback I guess my nephew was saying the dogs were in the house one of the dogs laid next to the bird and comfort the both of them so I'm not sure what happened but there both alive a swimming now after 3 hours of keeping them warm and cuddling they were in shock poor things whatever it was they were shooken up
