Introducing Standard with Bantam Flock?

[Rooster Rules]

Hi, want to add 2 or 3, 12 week old Barred Rock pullets with my 5 Bantams, 2 roosters, 3 hen/pullets, born June 2012.
Coop is 6ft X 8ft, it is very cold here now, so they have to stay inside. Some pics of my flock.

I have standard and bantams mixed in my flock. 10 bantams and 50 standards and everybody seems fine. Go for it

Quarantine first! Make sure they arent sick, so keep them separate for a few days, then, at night, stick them in the bantam coop with the lights off. And thats just about it..
