I have a flock of 3 older hens (2 years) and six 11 week old pullets. The pullets currently spend the day in an enclosure next to the main chicken run where both flocks are able to see each other. This has been for about a week now and although I'm not sure what signs to looks for--I'm not seeing anything concerning and the older hens are mostly ignoring the young ones. What should I do for next steps? Should I keep them exposed through the fence a while longer? Should I introduce them without fencing in a neutral area? Should I introduce the younger ones into the chicken area under supervision only? I'm new at this and could use any advice. TY!!!
