Hi. place the young ones where the older ones can see them but NOT get to them. let them observe each other for about a week. Then slowly try introducing them watching how they behave towards one another. do NOT leave them alone at this point. if after you observed for a bit and everything was fine, then they can be intergrated. if not and the older ones were excessively aggressive to the little ones continue with the separation.where they can see each other. And continue trying the integration. There will always be a flock dynamic, lead hen ect. pecking is normal but things to watch for is aggression. Jumping on the little ones, flying at them, aggressive behavior. Keeping them from feeding ect. Those things can seriously hurt or kill the chicks! I'm in the same situation you are with integrating the babies and this is what I'm going to do.Congratulations on your order!!!
super exciting! I just placed my order for 7 barred Rock females from Meyer hatchery. They ship out April 11th. Who did you order from? Did you choose to get yours vaccinated for Mareks disease? I got mine done. only .50 cents per bird. very affordable. I hope you show some pictures when they arrive!! I can't wait to see them! Best wishes to you and your new little ones.
