Yes should be very good, however I had some organic Burns welsh meadow I think it was and my buns weren't impressed - it actually smelt a bit yukky so they turned their noses up at it and ate the cheaper bog standard meadow and their oat hay - I suppose it just depends on the quality of the end product but, in theory Organic is always better but, more expensive sadly.
ETA most hay for animal feed isn't sprayed with pesticides etc as far as I'm aware so pretty organic anyway I thought :?
