After introducing 1 day old chicks to broody mum,which went perfectly...thank goodness..i am unsure when is the right time to put the other 5 hens back in with them..the chicks are 2 weeks old now and feeding well.. the other 5 are currently in an extension to the main run..and have ample room to go about their business,but would like to get them all together again as soon as possible. The hens consist of 3 black rocks one of which is mum to 3 young black rock,and the others are rhode islands..thank you for any help...Lorie
