Cochins are gentle souls and I've not had a mean one. I no longer raise them so I can just go from having them in the past. One of my very favorite all time birds was a gold laced cochin. He was beautiful and very docile. I would keep him unless he starts acting aggresive.
I used to use misters all the time. Even bought a huge set up to do several feet of misting at once... which I promptly missplaced and haven't ever found. I use pans of water, trash can lids, cut off barrels etc for the birds to stand in. When using a mister use them outside where it will dissapate... not in the coop itself. Using one in the coop can create a higher heat index and cause respiratory problems for birds. Great cooler outside though. I like using fans. Chickens can handle the heat if there is a breeze blowing. It's those hot humid still days that kill them.
I tried misters at one point & the bad thing is that after awhile the water in the hose will heat up so you're just spraying hot water at them, not a good thing.
It has been really hot & still lately, it's hard to breathe when you go out, even in the evening. It's no wonder the birds are having problems. I just don't take this heat well at all & I come in just soaking wet & done in every evening after chores. It takes about all I have to get finished.
