Adopting a broody stray today -- how do I mix her in with my flock?

[Shrader]

A woman who lives near me has had a Rhode Island Red living in her back yard for the past few months.
She's not sure where she came from.
It sounds like she's broody -- she's been sitting on a clutch of eggs for a week or so.
I'm going to pick her up this afternoon.
I have 4 hens right now.
What's the proper way to mix a new adult hen in?

Thanks!

Quarantine, quarantine, quarantine. Keep her separate for about 1 month to make sure she doesn't sicken your whole flock. For now a dog crate should be fine.

Wow, a whole month! Okay. Thanks.

I agree keep her away from you flock for at least 30 days. Watch for signs of infections etc... Then you can put her with the at night when they are roosting. Keep on eye on them in the moring.
