Turkey's can be aggressive with chickens too.
I've read stories of perfect harmony and of blood baths.
There's a sub-forum for turkeys, might do some reading up there: https://www.backyardchickens.com/forums/turkeys.20/
I had my Wild Eastern Turkey with our chicks of the same age for the last 5 weeks. They got along great. We got 2 more Wild Eastern Turkeys a couple week younger than the first and put the 3 together, the older one is really mad about being separated from the chickens and has escaped and rejoined the chickens several time. His name is now Houdini.
