i’m confused. he/she is grey? what is she/he?

Quailer is a rescue bird a woman on Facebook found in her garden. I feel bad every time I have to pick her up because she absolutely HATES me. She just acts so weird sometimes and I want to make sure she's ok physically.

She is my only bird with a name because she came with the name which is very fitting. She's a beautiful white lady who knows how to use her voice 😂 she is very happy in the covey and loves taking sand baths more than any other bird.

Can anyone provide critique of my quail coop?

We have 2 males and 1 female, they're all split up at the moment (hence the cage in a cage). We plan to get more, this was a bit unexpected.

I made it 8x3 ft with plans to add a center wall to fully box in 4x3 and have the rest be unboxed.

I was considering putting a wall to split it into 2 runs that are 1.5x8 ft. That way both males can have a run right next to each other with inside and outside.

Should the boxed in part have a floor during winter? I'm worried of draft but know they're cold hardy
