Introducing chick to roo...suggestions?

[Briarpatch]

We adopted a 1 year old roo from a friend and he has happily been living in our coop (alone) for the last few weeks while the 7 chicks have been growing. They are 4.5 weeks old now and I'm planning to take them to the coop this afternoon. Any suggestions or things I should expect? I'm a little nervous about his reaction. He was very protective of his hens in his old flock.

Whenever I have introduced new chicks to the flock, my Roo has always been very gentle and curious. Now, my hens, not so much!
