Wild Bird House

I have a lost wild bird in my house trying to take care of it?
my wild bird is a baby i feed her food that i know that its ok for her to eat but her poop is turning light green is that bad?!
please help!
If the bird is fully feathered, it is most likely a fledgling and has left the nest on it’s own and it’s parents are caring for it. You need to replace it where you found it..preferably in a scrub or tree so it is relatively safe from predators, and the parents should come back to feed it. If it is unfeathered…then look for a nest and if you can find it…replace it into the nest. Do not worry about your scent being on the chick..birds have a very poorly developed sense of smell and will NOT reject a baby that has been touched. If you cannot find a nest, get the bird to a local wildlife rehab for it’s best chance of survival. Also, keep in mind, it is illegal for you to try and raise this bird on your own. Look up a rehab here if you need one:
