I often pop some corn (or a tomato, bit of cucumber, whatever) in the nestbox with her, so she can eat while brooding. She seems to appreciate this.
Poppy sometimes tries to steal the stuff, and Gloria doesn't do much - if anything - to stop it. This is most unlike her, and is just a feature of the single-mindedness of the task in claw.
Why am I telling you this?
Well, I've now progressed to opening the dividing netting (between Poppy/Gloria and the Littles) each morning, and leaving it open all day. I can see that Poppy isn't happy. She asserts herself every so often, but I think that 3 newbies in one go is a bit too much for her. Now she has access to the newbies area, she comes as close as she can to the house, presumably for our company. I've also seen her sitting next to Gloria's nestbox.
The Litlees love the extra area. They especially love the covered run, and seem to spend a lot of time in there, rooking around on the ground, or sitting around on the many perches. They haven't noticed Gloria sitting in the nest box. Or, if they have, they are blissfully unaware that she's only letting them get away with it because she has a more important task to manage.
