My chicks are about 8 weeks old and have always been together. They've recently started to "challenge" eachother by getting face to face and stretching their necks out, chest bumping, and kicking their feet forward at eachother. One chick does it much more than any of the others. He (I'm assuming because he is so fresh...
) is also pecking at the others. Usually one quick peck and the chick he is pecking sorta yells at him, and he backs off. I'm worried because he is the only one that actually pecks at the others. Is this normal? Is it okay as long as it is only a quick peck and he isn't pulling feathers or drawing blood?
I appreciate your help! Thanks!
