Moving rooster between two flocks of hens

[Mrs. Mucket]

My chicken shed has two separate coops with a storage room in between. They share a run divided by 2" mesh with one group on each side. (Each flock has their own pop door into their own coop.) So all my chickens can see each other through the fence for most of the day.
I have one rooster. He has been in one coop with 8 hens. I'd like to get some fertile eggs on the "other side of the fence."
Since they all are familiar with each other, could I just move the roo into the other side for a couple of weeks with those hens? Is that likely to cause any problems with the roo or either group of hens?
Could I switch the roo back and forth every couple of weeks without problems?
Thanks for any thoughts or advice!!

Initially there may be some confusion and conflict, after that things should settle down. If he were mine, I'd leave him in a pen for a week then switch to the other. That way the eggs from both pens would remain fertile.
