So my dog found this little bird, which fell from mid flight or maybe it was sitting on a branch, I don't know, and brought it to me. My dog didn't bite it or hurt it in any other way.
It's a really small bird barely even fills the palm of my hand. I saw it couldn't fly properly or even sit upright so I took it in. After checking I realized that the nail/ claw on one of its feet on the third digit is missing. There are no other visible injuries and it's wings are working just fine. So my guess is, because of the missing nail it can't hold on to anything and perhaps it's also making it lose its balance during flight.
I really have no idea whatsoever of what I should do in order to help it. For now I'm just keeping it in a makeshift cage, gave it a soft place to rest and some food and water; I couldn't just leave it because there are many cats in the neighborhood.
I would really appreciate some help and advice with what I should do with it.
Also if birds lose their nails/ claws like this do they grow it back?
I've really been worried about this, so any form of your input is welcomed.
*UPDATE: it can't even fly properly, just like a few meters at Max
