My baby chick just hatched and it has a bump on the head, is it the brain and do I half to kill it?

i have seen baby chicks that have that problem it could be genetics or like you said could be something that has to heal in time do some research on the issue to see what it might pertain to you could also try to contact a farmer maybe they have seen this unless you know a vet that will look at it and tell you if they have any problems that has happened because of this it might be a deformitory of sometime
