Hello I have two 6 week old Barred rocks that I have been trying to add to my flock of six thirteen week old cochins. So far I have been keeping the two chicks in a cage with their own food and water in the run.When they are in their cage the older ones seem to leave them alone and there is no pecking. But when I let them out into the run the older ones show more interest and peck them more often. Also the little ones don,t follow the older ones when I let them out to free range (they actually follow me). And the older ones kind of run away as if they are abandoning them. I also still take the chicks inside at night in fear they will be afraid being locked in a dark space with six other chickens. What should I do? If anyone has any addvice please tell me thanks.
