We found one dove from outside so I want to know how old this bird is and what I can do for it?
I searched the internet and, based on it's photo shown below, I think it must be an adult.
This link suggests feeding carrots:
Doves should be offered fresh fruits and vegetables alongside seeds and pellets. These add diversity to the bird's diet and give it a wide variety of nutrients. Some items to give your dove include lettuce, kale, broccoli, carrots, and apples

How long does it need to stay with me and what care does it need?
Update:
It has been better, although one week ago when I let it to try flying in my room, it's left wing has been fixed but now it has been stopped.
I am scared and haven't let it try flying in my room again so I put it in a cage in our house yard. Here are some pictures of it:
And this is its food (Is this enough / too much?):
I would greatly appreciate it if you kindly give me some feedback on this question.
