bullying problem

[king tail]

i had my hen, Lacy, in with the other chickens and decided to let her free range for a wile.she went broody and i put her and her 3 chicks in the pen next them. shes been there since September 6th 2016. i decided to put her back in with the flock and they are really getting after her. i dont know what to do. shes been with them since the spring of 2015, i only had her out for the summer and shes been right next to them for about 4 months. i thought they wouldn't be to bad. but they are

thanks
