there were three bird's on the grown and the mom try to save it but it keep falling down and all most killed then I took it inside the house and feel it with bread and water.So I don't know much but I need your help to take carry of it plz!!!
Bread and water won't do it - can you replace the nest securely where mom will find it? The myth that birds won't take babies back after they are touched is just that, a myth, so she will take them back as long as she can find them.
Barring that, it would be best to find a wildlife rehabber to take them. They are going to need round the clock care and special food made for them.
