New Hen keeps pecking my original 8 hens?

[MckinneyTXBYC]

[FONT=Verdana, Arial, Helvetica, sans-serif]We got 2 new hens that around a month to month and half older than our current hens.
One is a red star sex link and the other is a black star sex link.
We already had 4 red star sex links and 4 speckled sussex since they were a week or 2 old.
So far the new red star keeps pecking nearly all the hens as far we
can tell and the black star is not doing this.
The new red star hen will just come along to any hen sitting down or
eating and peck them to move.
We notice the pecking hens like to peck on the speckled sussex the most it seems.
Also we notice the 2 new hens keep to there self away from the other hens.
Should we [/FONT]isolate the pecking hen in a dog kennel by her self for a week and then see what happens.
Thanks

I would say not, they are just trying to be dominant which they will soon be cause they are older.
