Can you give us more context? My chickens like to peck on painted toe and finger nails, rings, and things that shine. Mine also peck me when they're hungry or want what I'm holding (hoping that it is food). Or it could be in a more aggressive way like biting you repeatedly with angry squawks and or spurring you.Does it leave you alone if you leave it alone? If so, might just chalk this one up to not wanting to deal with the humans and just enjoy it from a distance. I have one girl like this in my flock that she REALLY does not want to be held. But she will still come hang around when treats are offered.
