egg laying questions!!!!

[bayleef13]

My female magpie has layed a clutch of 9 eggs so far and occasionally I see her near them In the morning but she hasn't started sitting, is she waiting for her clutch to be larger before she begins sitting? And should I block her off from the rest of the flock with her eggs when she starts? Please and thankyou!!!!

Well I'm by no means and expert as this is my first time with a broody hen, but my Pekin hen waited until she had a clutch of 12 before starting to sit full time.
