Hi guys...quick update. Since the new girls had been in quarantine at the vet/shelter i got them from for >1 week, I kept them separated from the rest of the flock for a further 5 days in their own coop and run. Today I put them in with the rest of the flock. So far there is no blood but man the rooster is pecking the heck out of them...i think comparing their weight/feet/comb size/feathering and overall body size with my own birds Im guessing they are around 12-14 weeks old.
I know the pecking order has to be sorted out i just hope they dont get seriously hurt in the meantime..the run they are in is 40x30 feet, and has 2 coops and plenty of roost space in it for the birds...there are now 26 chickens and 5 ducks in there. ( roughly 40 sq feet per bird of run space give or take.)
