My four chicks will be six weeks old on Tuesday and although pretty independent during the day, (especially the boys), still come running at mums call and tuck up under her every night and also for naps during the day. Mum is more than happy for this to happen and is still watching out for them during the day and not showing signs of ignoring them or trying to get away.
When mum returns to the other two adults, she will still be within sight and sound of the chicks and also has the added issue that both the other two (silly idiot) adults are broody

When should I remove mum, should I do it at night (as you would when introducing new chickens) and is there going to be fireworks as I'm introducing lone chicken to a flock, or with chicks and mum desperately trying to get back to each other as they are within sight? Cheers.
