our littlest barred rock (3 weeks old, same age as others but almost 1/2 the size of our biggest chicks) is starting to peck at others. first it seemed to be just when they would get fresh food - she would try and snag stuff from other chicks beaks. now my partner says it looks like she is starting to move from beak exclusivity to pecking the general face area.
they have plenty of food available to them, and we switch water out a lot. there are 8 chicks total and their current home is rather large and gives them room to try and learn to fly (which they love to do!) and they have a little roost they all enjoy to play on.
any suggestions? ideas? should we pull her away for a little bit?
