Don't feed your layers anything medicated. If you do toss their eggs.
Why are you so worried about your sebright getting Marek's? It seems you're convinced she's going to drop dead at any time. I do not vaccinate my birds and I have no problems.
Also get rid of the roos you aren't going to keep. It really needs to be done soon and before their hormones really kick in. Get your flock consolidated before winter and be done with it. You'll also need to start making sure the roo you're keeping respects your place as head of the flock. No need to be mean, just assertive.
