Tilda was very actively exploring the kitchen; it wasn't raining outside anymore, and I decided that she really was well enough to go outside for at least a few minutes.
I walked her to the door. She didn't want to go where I wanted her to go, she kept trying to dart round my legs. She's obviously feeling well enough to be trying to assert herself.
So, I persisted. Eventually, I had walked her to the door. I walked her a little bit more so she was standing on the ledge. I walked away. She was back in the middle of the kitchen floor in moments.
So, I tried again. This time, I walked her all the way outside (I stood behind her until she hopped off the ledge down on to the patio).
By the time I had got back to the kettle, Tilda was back inside.
Hmm.
I'll leave it for a couple of hours and try again later.
I filled her food dish and she's back in her pen stuffing her beak at the moment.
