She's probably fine . . . just beeeeeeeeeeg

in the belly. I had a similar thing happen when all my (new) goats came in from browsing, I'd had them for several days. It was June in north Idaho, and the green stuff was really getting underway up in the mountains. I had a herd of goats as wide as they were tall. Just fine, eating and drinking, just huge.
A goat sick with bloat will not eat. She just stands there and stares with her tail down. She obviously doesn't feel good, and she may or may not have a huge rumen.
I made a STUPID mistake and overgrained my doe on the milk stand the other day so I could clip her hooves and have her semi cooperate. Then, I'd just moved the kennel panels to a brand new patch of browse that day as well.
She's chewing cud and on her feet, doing much better but she was obviously sick and there was no question that she was. Next morning, there were a few diarrhea poos in their barn.
I'm going to withhold grain until I see normal goat poo.
A sick goat and a goat who's spent a day eating lots of browse is a different animal, and again I got the reminder
I think your girls are fine.
