Right levels of calcium in Readigrass?

I'm buying a healthy (daily) "treat hay" to vary the buns diet a bit, but have heard it has too much calcium despite Readigrass claiming the calcium levels are good (picture attached)? Is this really the case? Could I feed a little daily?View attachment ImageUploadedByRabbit Forum1454956588.548545.jpg

Looks like overpriced lawn clippings.....

I think there are much better and healthier treats out there that cost much less then bagged grass...
Most people buy bales of grass hay from tractor supply stores. A great treat would be... cilantro or something yummy and cheap.
The protein and lack of fiber are what stick out to me.
