I've ordered my bantam Columbian Cochin trio and am ready to start my backyard flock (half acre) I'm doing a movable hutch and also have a large fenced in flower garden (picket fence) for some play time. I came across a line of bantam Black Rose Combs that are descended from my Grandfathers flock and couldn't resist getting a trio of them as well Question #1. Is it true that chickens won't perch (or fly over) picket fences? Question #2. Will my two families of chickens be able to co-exsist in harmony? (I plan on having them in separate hutches but they will be around eachother and can see eachother. Question #3. I've heard over and over how docile the cochins will be and I'm somewhat concerned about the rose combs. I want them all to be my sweet little pets. Any insight to their personality?
