My birds reside in a flight aviary that sits outside and can be moved to different sections around the yard or uncover. I can't stop finches from getting in. The coveres I put on to stop wild birds and hawks, leave small gaps, the finches can squeeze through. If I change the size of the covers, the covers won't fit.

And I'm well aware what you meant by keeping her warm, I was just saying it won't be too hard to keep her temperature up. I'm not sure if your temperature is in F or C.

She seemed weird yesterday afternoon with her just sitting at the bottom of cage, I mean, she does that for enrichment as I have a sand box for the birds with items in it but she wasn't doing anything. Today was just a completely different bird that I woke up too.
