She has been on fresh, wet pasture. Usually her belly isn’t this big after she’s been out on grass. Acting totally fine/normal otherwise.
Both sides of her belly are soft, but it feels like there are large uneven lumps, especially on the right side (the photos don’t show it very well but it definitely felt weird). Her left side also rises and sinks (as seen in the second photo)
The other goat out with her has a normal belly & appetite.
