Of our 3 young chicks which were integrated into the flock using a broody hen, 2 of the 3 turned out to be roosters. We exchanged the roosters for 2 Plymoutth barred rock hens (20 weeks old). Our remaining hen from the new chicks is 16 weeks. The 3 chicks used to stick together, and our original 4 hens have their own group. Now that we have removed the 2 roosters and adding the 2 barred rocks into a seperate enclosure. Is it best to add the young hen with the barred rocks to create a new group? Or leave her with the original 4 hens? She is clearly at the bottom of their pecking order but it is not aggressive. I would appreciate any thoughts/advice! Thank you!
