Went back to easing her into pasture. Put her into a pasture the rest of the herd had already eaten down with a bale of hay so she had some of both. Then moved her to a pasture that had been eaten down a bit without any hay. Now she's running with the herd. Either this is done the trick or I'll find her bloated and dead one day. If I have to do this every spring though her days are numbered anyway.
