I have my 2month olds outside in a penned of area where my older hens can see them. When I went out today to check on them I found one of the babies heads had been pecked on badly and it's beak is a little off now. I have no idea how this happened. I don't think any other animals could get in at them except maybe one of my red sex-links maybe got at it some how. I've cleaned up her wounds and brought her inside. She seems totally fine. She doesn't act like she's in pain and she is still eating. Will her beak ever go back to normal or is she permanently injured? Is this something she can live with if she continues to eat or does it get worse once it starts?
