Picked up 3 black sex link pullets at tractor supply 3 weeks ago. Can anyone confirm this is a pullet? They are all 3 mean but this particular one pecks all my other 8 hens, minus the 2 other black sex links. The others all have a raw spot on their back from where this one constantly pecks them. The others run everytime thi s one comes close. Is this a hen? And what can i do to stop her pecking?
