The Hay Appeal
One small square bale costs £3 - £5 which lasts approximately 2 days for one horse. (This is averaging it out as we have so many different sizes of horses. A shire sized horse will eat a whole bale to themselves in a day when there is nothing else at all to eat but for a Shetland it may last 4 or 5 days.)
A large round bale which is equivalent to approx 10 small bales costs £25 - £35 (this can vary depending on the quality of grazing it was cut from) so the round bales are more economical when they are available.
