Keeping Chicks with Pullets?

[TheRoyalRoost]

I’ve got three pullets and two cockerels that are seven weeks old and already in the outside coop. I also have two three week old chicks - one bantam Cochin and one frizzle. At what age can I mix the little nuggets in with the big girls?

It may be too late to put them all together. That would have been more possible if you had put them together when you got the new ones, as there is a "window" where chicks accept one another up to four weeks of age.

Now, you can expect the older ones to terrorize the younger ones. I suggest keeping them all separated until they all reach approximately the same size. Meanwhile, let them get used to one another through a see-through barrier.
