I am sorry for your loss. All you can really do is try to think of ways to make sure your remaining chickens are better taken care of. (Not that you did a bad/poor job, there's just usually some place you could improve.)
I started putting out a baking dish of water for my chicks when it got so hot. They liked standing knee-deep (at a couple of weeks old) in the cool water. My big chickens usually got their run washed down until puddles were left behind. I am seriously considering a kiddie pool when they go on clearance. No, I don't have ducks nor plan to get ducks (I remember how dirty they get!!!), but I think the adult chickens would enjoy standing in cool water as much as the chicks did. With my luck though it'll probably be cold all next Summer and they won't be able to use the pool.
Anyway, enjoy your chickens. Don't be ashamed of your feelings for that rooster. It shows you cared for him. Be blessed!
