A week is not too late as long as no eggs are under them right now. They will stick with the clutch to hatch according to everything I have read. But you don't want to slip eggs in a week later once you have eggs under the broody or adding those eggs will cause problems at hatch. Either she will abandon them to help her new chicks or ignore her new chicks to wait for the unhatched eggs. I don't know about keeping them separated. My guess is it will depend on your flock dynamics, and how many predators the momma will have to defend against.I have 2 broody silkies. They have been broody for a week. Can I put some EE/maran eggs under them now? Or will they stop being broody too soon to hatch now that they are a week into it? I would love to get olive eggers. Also, if they hatch how long should I keep them away from the rest of the flock? Mine are free range so I would hate to keep them locked up. Thanks for your help!
