She is one week old and she pecks at everyone (I have nine little chicks 3 days to two weeks old) a little bit everday but today i noticed her pecking at the largest chick i have in there, which is a 2 week old Black Australorp, to the point where the Australorp is missing a tiny space of feathers. Is this normal? I really thought this behavior didnt start until a bit later. Ive also noticed that she was stretching her neck to try to look out of their little habitat and jumping up trying to fly as if she's trying to get out?? I have no idea really, just speculating, but she seems to be a bit precocious. Any suggestions welcomed. Thanks.
