Lol no fortunately its not too cold here ... gosh if it was like that she would still be inside overnight!
She is continuing to get stronger, is now back with her siblings this morning (basically because she demanded it, and we figured if she can demand that vigorously she is ready), and is doing very well.
She's steady on her feet, has good appetite, is keeping with the flock, and looks all healthy again (still needs to put on weight of course, and we're feeding her up).
They've all been wormed and will be again in due course.
No problems with her siblings ... in fact they're amazing. I don't know whether this is normal for geese or whether we have a very sweet bunch, but there is never any bullying. I've never seen anything like it in any animal before ... not one of them has ever so much as looked badly at another. Even over feed they are gentle, peaceful, ask nicely, and step aside to let others in. In fact they make sure everyone has a fair share. If only human children were that good at saying Please and Thankyou!
When Pilly was weak they were careful of her, at least when they were near her, they would be gentle and slow, stand next to her talking quietly, and show every sign of concern if she tripped ... very strange.
Now she is back with them they won't let her out if their sight, they're keeping an eye on her and there is always a goose next to her ... very caring creatures apparently. I've seen roosters that sit by sick hens before, but never a whole bunch of birds behaving like this. And she is much happier for being back with them. At this stage I think her flock can give her the care she needs best. Lucky girl to have such a sweet bunch of siblings!
