It was lying about on the grass, trying to flap its wings near my neighboor's cats, so i grabbed it and got it a shoebox. I tried to chop up pieces of soda crackers and put a cup of water beside it, but even when i came back from work it was just sitting there.

My friends tell me it isnt sick, because when you try to hold it, it tries to scamper away and flaps a lot, but never picks up enough speed to fly off.

First off, how do i feed it? I got a bunch of bread and i think i have milk powder, dunno if i should wet some crumbs and place it in the shoebox...

Second, i am wary about it having fleas or parasites. Should i give it a warm bath in my handwash basin?

Third, is it normal to be this quiet and unmoving for quite a while when i put the lid on it? The lid has holes.

Heres the bird in question.
