Wild Hen trouble!

[GrayChickens]

So I live in a realy rual area. And on Valentine's Day 2020 I found and captured a wild American game hen that had been wondering around my yard. I decided to keep her and immediately began the quarintine process. We bonded alot through that time. Then I bought a chicken leash and took her around my property and she got along well with my other chickens. I now consider her fully tame as I can just go straight up to her pick her up and hold her she is realy friendly and comes up to me. She is now apart of my original flock BUT she won't sleep in the coop . No idea where she goes at night but she is always is back in the morning. It's like she still knows she is wild how can I fix this.

The only thing that I can think of is to keep her locked in the coop/run for a week or so. Hopefully she will become accustomed to sleeping there.
