I found this little bird today, I went to work on the first day of today, and then I saw this bird in the cracks in the glass window of the factory Reed, and it was estimated that it would not be able to come out for a few days, very thin, fed a little water, did not know what to feed it, did not dare to let it go, and it could not fly, and its feet were broken, and there were many wild cats in our factory.
