Helga laid another egg in the morning - off her sleeping perch instead of in her new nest. It splatted onto the cage floor. I found her sitting on her empty nest, looking glum. Silly bird, that way she'd keep laying eggs forever because she'll never get to a point where she feels there's enough of them in the nest. She'll be like a battery canary!
So I put a glass marble that we found in the swimming pool last week into her nest when she was out next - she looked very surprised but after some deliberation and very quiet chirp?chirp?chirp?chirp? noises sat down on it. All good now. One egg in the nest. I've got another marble somewhere if she splats another one tomorrow.
