I have Rose here who sometimes does this - acts like a Sarj. Major and shakes things up.I feel for you, but frankly my reaction to this is that it actually looks pretty ho-hum and relatively harmless - but I'm comparing it to the roosting situation here, which amounts to the Spuds running the Buckeye gauntlet every evening getting into the coop, and it's not that hunky-dory between the Buckeyes when they roost, either. What you've got going on looks like a routine bed check from this perspective! Aurora comes in like the drill sergeant she is, does a little re-arranging and reminding, then leaves. But everybody expects this and settles right back in.
I'm not clear on your comment, what could Lady F. not do in the coop? I thought it was Lady F. on the upper right roost, next to Glynda. That's not her? Those two don't have to move and stay there the whole time, happy as clams. Hattie was made to move, but she's also acting like this is no big deal, in fact she inspects something up in the ceiling while Aurora patrols, and then gets back in her nest box soon enough. Phyllis comes back in too, soon after Aurora leaves. Seems to me nobody is taking it horribly badly or is even getting pecked hard. I didn't hear any squeals or squawks.
Would you consider putting a thicker layer of straw down for Hattie? She is plopping on to the wood kind of fast and hard (arthritis in her legs/hips, right?) and it looks like she's tipping to one side or the other to accommodate her keel.
I noticed that even though LF didn’t move she and in fact all of them where on high alert when HRH came in, she definitely is not welcome around them that’s my take on it. If you notice they all in fact keep an eye on her and when she gets within striking distance they move off. LF remains on her roost but if HRH had pressed the matter she would have moved - I found that very interesting and I wonder if LF will become leader in the future as she gains experience and status in the group.
Hattie would likely do what my chooks do with a straw bed - dig it out and chuck it all over the place. Unless it’s about 8” deep they just make a mess of it. What I did with Red in the feedroom is give her a fluffy towel to roost on, it gets poopy but I just let the poops dry and they flake off, I wash it every so often. It really hard to find something they will want to roost on, even Penelope who I wish would stay in a nest box full of straw won’t.
