That 10 year old vegetarian sounds like she needs a lesson in animal cruelty. Maybe she doesn't understand that the birds are freezing to death, and that they, as their masters, are guilty of cruelty, and could be fined/jailed? To bad the neighbors allow the child to influence their decision to the detriment of the animals.
I'm a Vegetarian and even I agree with this. That is just not right. You can't just go and be a Vegetarian for animal's sake, and then let your own animals freeze to death.
It's just wrong!!!
But anyway, if it were me, I wouldn't be able to stand to watch that poor rooster out there. I would put on some thick. protective clothes, boots, and gloves, and go out there during the night and catch him and bring him inside. If you're worried about him being mean, just catch him at night because that way he can't see you and he won't be able to attack you. But he probably will bite to defend himself, so wear gloves. You could catch him and keep him inside your house in a kennel with food and water and keep him there temporarily, and then explain to his owners that he doesn't deserve having to stay outside in the cold and freeze to death, and maybe offer to take him off their hands and give him away to a loving home?
So that's what I would do. Catch them during the night, when they are all sitting in your tree. Use gloves for safety. Bring them in your house and put them in a room in a kennel or big cardboard/plastic box (temporarily). If you are really worried about going over to your neighbor's house, call them instead and explain to them that you're not going to stand by and watch those poor roosters freeze to death (say this as nicely as you can.
) Offer to take them off their hands for free or for a small fee, if they really insist on that. Then, it's your decision to either keep them/some of them to try and train them and teach them to be nice and add them to your flock (it can be done), or sell them/give them away to another loving home.
Lastly, for the remaining chickens, I would definitely call a humane society and explain to them what has been happening and everything.
Good luck!!!! I hope you can get those poor roosters out of the cold.
