Henpecked?

Got 4 girls last night from Merrydale 2 Sweeties and 2 Schwarz (pls visit merrydale link to assess breed as I'm unsure and presuming these are 'brand' names)  All 4 were put in the coop yesterday evening and let out around 12 noon today (didn't have the heart to keep them in any longer) The 2 sweeties (24 wks old) seem to have settled in fine but the Schwarz's (18 wks old) seem a little timid but doing ok.

Question is one of the schwarz has had her comb pecked and has spread a little blood around the coop.  Is this just the birds establishing the 'pecking order' or something more serious that requires attention.

One of the sweeties seems to have established herself as 'top hen'

BTW I've had one egg from one of the sweeties already    

I know its a legal requirement to post some pics, I will do this soon  

Any info on the breeds would also be appreciated.
