How high can american game chickens fly?

[Matejka]

Recently acquired 2 chickens I believe are game. How high can they fly? They are currently in isolation, but I hope to integrate them into my small flock of Australorp and new hampshire. Will they return to coop at night to roost? Or return at all? How much fighting will these 2 do with the established flock? Many questions and I couldn't find my previous post an[it them being wilder tthan March hares.
Thanks for any advice

My neighbor has some, they roost on top of his barn and in his trees. He says they fly over his seven foot fence easily. He also says the only ones who fight are the roosters, his hens are relatively calm.

Thanks! I had them quarantined, somehow, the door did not get secured, and they escaped. I have seen then about 20 ft up in the trees, they are returning to roost in the barn at night, I have seen them drinking and eating in the coop during the day.
They are gaining weight, and filling out. I "may" go out one night after they are roosting and try catching them. Not sure yet.
