At what age can I transfer my chicks with the "big girls"?

[BirdGirl2004]

Hey guys, My chicks are around 9-10 weeks old, and I was wondering when they would be okay to be transferred with the older girls? Should I wait another month or so? They look too small to put with the larger girls. Also... please don't judge my coop lol, I have redone it since then

Larger girls ( and boy )

Chicks:

Thanks so much!!

I put my SLW's in with the flock at 10 weeks. At week seven I started letting the youngsters out of their pen to roam around the big girls run. After about a week they lost interest in them for the most part, thats when I let the girls out to mix with the youngsters out in the yard. They had some issues but after about a week or so of this they got along ok. So when it all seemed good I too the kids and stuck them in the coop after dark. Next morning when I let them out they all came out together and milled around the feeder and waterer. The big girls made sure they knew who got to eat and drink first, and there were some small issues with the lower girls on the pecking order trying to bully but my lead hen straightened that out
