when to ween from mummy hen?

[wcah]

I had a broody hen and her chicks hatched 6 weeks ago. I took the broody hen out of the main run when she started sitting. Mummy and her 3 chicks have been in a seperate coop and run and the main group are freerange so have seen them and cogragate around her run. Theses last couple of days mummy hen has been more agresive towards her chicks and the cockeral keeps running over to see what the cufuffel is all about, also mummy hen is laying again. Should I put mummy hen back with her gang and leave the chicks where they are for now or put them all in together? Then chicks are stil sleeping with mum and havent started roosting yet when will this happen?
Many thanks

If she's laying again the time has come.

Moved mummy hen last night and shes been happy running around with her mates. Chicks seam happyer too now they arnt getting attacked and look much more relaxed. I have bought some grower pellets which ill mix in with there chick crumbs for a week. What else can i feed them? can they have bread, mixed corn, vegs scraps, pasta,. Is there any toys or play things that i could put in to stimulate there minds?
