Sunkiss below is a single factor, red factor sun conure and she is about to lay an egg!
Notice the big round egg looking bottom of the bird, and the wings are held slightly down. Sunkiss always holds her wings lower when she is about to lay, maybe its the discomfort of having such a large egg in a small space.
