Adding an older rooster with younger hens?

[silvertitan]

We currently have what I am assuming are 6 hens (we just started getting eggs this week and found 4 today...so at least 4 hens?) We have an Americauna, 2 Black Sex Links, 2 Golden Sex Links and a Silver Laced Wyandotte.
A woman has a 2 year old Silkie rooster that she is getting rid of because they have too many birds now. Will it be ok to mix an older rooster with younger hens? I am also a little concerned because all of our chicks are extremely social, come running when they see us and follow us all over. I don't want to get a rooster that will be rough with us if we are dealing with the hens or worry about him being rough with them.
Any ideas, is this a bad idea to add him to the mix or should we be ok?

You should look over her flock carefully for sign of disease, then quarantine him for several weeks. This article speals to both quarantine and how to mix birds after quarantine:
