We make our own, but if I do need to buy in then I purchase the best I can get my hands on. I will not consider feeding crap hay to my sheep but there again they are kept more as pets then as a small business venture, so I try and give them the best I can in all respects and a small profit at the end of the day through selling my lambs is all I ask for and is a hobby more than relying upon it as a source of income. By taking crap hay you are risking ragwort and all sorts of horrors which I personally do not think is worth the risk to the overall health of the livestock.
