Sounds similar to my mare. Just gotta keep a close eye. I leased out one of my favorite mares for breeding. She foaled and died a month later. I was devastated. Really loathe colic
She may have. I had a mare that would get gas colic. She'd just get lethargic and go off feed and water. No serious rolling, but she'd lie down and just stay there.
No rolling, kicking, biting, or anything like that. She's just tired acting. Gums/eye mucosa are nicely colored. Honestly, I'm wondering if she didn't get heat exhaustion
She did it when I was touching her right stomach flank. Unsure if she's being guardy from pain or just guardy since she doesn't feel good since that's where one of her old surgery sites is at
