Any help would be appreciated. One of my baby chicks has clumped wing feathers. I have no idea what it is and I haven't been able to find anything. They are probably 2-3 weeks old.
Are you referring to the plastic-like binding around each feather? It's feather sheathing that hasn't come off. You can gently crumble off a little by hand, but it should come off on its own as the chick grooms itself.
