If you feed bermudagrass basically free choice, + smaller amounts of e.g. 1 flake ea (weighed) alfalfa and timothy per day, can you just almost fill a slow feeder (accessible only at the top, like a PortaGrazer) with the daily ration of bermudagrass, then put the other hay flakes on top? The more palatable hay would be eaten first so presumably no frustration for the horse?
Thanks
