We have a Black Jersey Giant chick that is 3 days old, and has scratched its head, parts of its neck and right wing raw. It stops for a while then starts scratching again. It does this off and on, it still eats, and drinks fine and regularly. However, we have no idea why it is doing this. It has been quarantined away from the other chicks in case its a bug or something. Any ideas on what it could be? We used pine shavings for the bedding, newspaper for the first two days. No other chicks have expressed the same symptoms as this one.
