Sorry don't know of anywhere but if you find any please could you let me know - we are in the same position. As most of ours were burnt the yard have started using this years already and I just can't risk that.
We are struggling for hay as well, we've just been told our normal supplier can't do us this year, he is so short on hay he just can't spare any. I may be able to get some next week but nothing concrete yet. Looks like haylege for us this year
