I was wondering about free ranging new silkies with older birds?

[Jferlisi]

So i have 9 chickens i already free range during the day. I got 2 silkies today and i was going to let them mingle with the girls and boys in there 24x24 with a 6x12 added corner run. I was wondering if i would also be able to let them free range or should i keep the two in the run for a few days till they know its home. They are 4 months so im told but it was getting dark when i saw them. Atm they are in a makeshift coop until i can make a real one for the new ones cause i dont think im comfortable with them being in with the others right now.

I dont let my silkies free range because of preds. they have lots of fluff by thier eyes and dont see well they also dont fly so they have to run from preds. they are not that fast.

In my area a free-ranged Silkie is a predator magnet more than any other chicken I've seen.
