My local feed merchant hasn't been able to source any, the only one I can find on t'internet is Saracens so I'll ask in Wynnstay and TFM if they get those. Otherwise?
You can order them online from: http://www.gardenfeathers.co.uk/cage-bird-straights/naked-oats-superioats.html but I have no idea how much they charge for delivery. A feed merchant near me gets me some every winter but I only know they come in a plain brown sack and am away on holiday right now so cannot check the label. I can ask him where he gets them from when I get back in a few days if you would like me to.
Thanks both, £6.99 delivery on those planete, and the northern equine ones, both worth bearing in mind. Saracen have Wynnstay down as stockists so I'll ask them tomorrow.
