OMG you all have me so nervous now ! My hen is in the main coop with her little ones - and there have been no issues at all though - I've stood for HOURS - Literally - everyday for the past 4 days just watching them for any sign of agression (They had been kept separate, but in the coop - maybe the see no touch helped? Momma was getting really really agitated and wanted to get out of jail - so I figured I'd give it a go with lots of supervision ). The big girls just kinda look at them and keep going about their own business. Even eating next to each other - the big girls seem to like the chick food "treat" that is on a big flat lid on the floor for the chicks to reach and scratch in.
