No but they eat the dry version - orchard hay
Not immediately but within the hour.
Ikea bag??? 2 to 4 cubic feet (We Americans will use anything but the metric system you know)
My husband started using a scythe a couple of years ago because he didn’t like the noise and mess from the string trimmer. I usually only give maresie a little of it, only what I’m sure she’ll eat while I’m standing there. My fear is her leaving some of it and coming back when it’s between fresh and dried, during the dangerous phase. Years ago, a friend of a friend lost several horses at once due to being fed clippings that sat too long, but not long enough to dry out. I try to err on the side of caution.
