My cochins are VERY sweet and docile!!! They are the friendliest birds that I have. The hens are very broody. They go broody at least 4 times a year if not more. They are very motherly and protective. I love these birds. I have nothing negative to say about the cochins.
I do not trim their feathers. They get dirty and wet when it rains but for the most part they are very clean. I live in the south (South Louisiana) and temps are sometimes in the 100's and have never had any problems with over heating. They lay about 5 times a week. They are very easy to handle. I usually have to move them when they become broody and have no problem with moving. They are so calm and docile, they let me pet and touch them while they are setting on their eggs and do not mumble one single word. They just look and set. I have NEVER seen any molting and I know that's unusual. But their feathers are always beautiful.
I wish my entire flock off 100+ were cochins.
