Since I frequently have a mixed flock of juveniles, plus a rooster, I do the oyster shells on the side. My rooster doesn't eat the oyster shells. Neither, by and large, do the juvenile birds. Indeed, one of the first signs I get that a pullet is getting ready to lay is that she becomes interested in the oyster shells.
I honestly don't know what, if any, the long-term consequence of roosters eating oyster shells are, but it's not very much trouble to fill up a dish of oyster shells every now and then.
