I am in the process of building up a new flock, after my previous flock was decimated in a dog attack. I have 4 Wyandottes, 3 hens around 20 weeks and an older rooster. And, I have 14 young chicks which so far are in a separate area in the coop. They're about 6 weeks old, Wheaten Marans and Lavender Orpingtons. The chicks have not been outside yet and have not been with the older chickens. What is a good time to integrate them? And is there a process that you recommend? Should they continue to have access to a separate space, through which only they fit, in case they need to escape from the older ones? Or once they are out, and if things seem to be going well, is it safe to leave them with the older chickens? At what age do they like to roost? I have a roosting ladder, and the older ones sit on the top row, so there are several rows left for the young ones. I've raised chicks before, but always with a broody mom who took care of them. I'm having to think this all through a bit more myself this time. And yes, the dog problem has been addressed. The dog had pushed his way into the run, which had a weak spot. We've rebuilt the entire run, with a strong fence, new chicken wire, and hardware mesh a few feet along/under the ground and up the fence, to deter digging. There has been no sign of the return of the dog, and no sign of any repeat attempts. It's been a few months, so we feel things are under control and safe.
