How to integrate chicks?

I have three six week old cream legbar chicks - 1 boy and 2 girls. I am a bit worried about how to integrate them in with my other three hybrids. Their foster mum is still quite happy in the broody run which is inside the main run so in full sight of the hybrids, but I am hoping to get them all out and about together in a couple of weeks. As the male chick is very adventurous he escaped between my legs and went off to feed with the hybrids and got a good pecking for his insolence. He ran off yelling and the two girls hid in the far corner of the broody run swooning like Victorian ladies! Is it best to get them all together early in the morning or leave it till nearly bedtime? I've a couple of weeks to gather any welcome advice, thanks.

Should I just go for it and see what happens then?

Hi,
    Am reading this thread with interest. I had 3 broodys with approx 10 eggs each but for reasons unknown they all came off at about 2 weeks and when i checked the eggs, 90% were viable. After this upset, i bit the bullet and spent £300 on an incubator so my question is how do i integrate the chicks with the rest of the girls if they don't have a "mum" to protect them ?

Thanks in advance.
