I have 4 faverolle hens and 6 buff orpington that are 7 weeks old or so. When should I put them with the if girls? What about layer feed verses chick starter? They have free ranged together and today I put them all in an enclosure together to see behaviors. I believe that they are ok. I was thinking 12 weeks old and I could switch over to chick starter nonmedicated of course for 4 weeks. Would that be ok? I'll keep food and water in 2 separate areas so there is t bullying for food.
