I have found a swift last night, she clearly has one broken wing. I have spoken with a few wildlife rescue foundations in my country and one accepted to take it in and help her. I will send her over there tomorrow morning by train but until then I'm scared that she won't make the night. She hasn't eaten or drank water since at least yesterday, from what i found on the internet it's not advised for me to feed her either. I am conflicted, should i try to give her a little bit of water at least or am I risking her health by doing that and will she make it till tomorrow morning? If anyone has any advice or information please help cause i really want her to get through the night.
