For a 12x14 stable and circa 8 inches in depth (More around the banked stable sides) I initially used 4-5 bales. I top up with one new bale a week. It's priced at £8 per bale at Countrywide Farmers. It probably works out more expensive for me with the horse, due to the fact that I could buy small bale hay at £1.50 per bale from my neighbouring farmer, but also the fact hat I do like the horse to have a deep, comfortable bed. I am also unable to use straw with him as he would eat it all and he does have a slight allergy to dust. I find cleaning the stable using Bedmax is so easy - it is much better than standard shavings as the wet doesn't spread so far and keeps the bed much cleaner and drier. I would definitely not use anything else now and I have tried lots and lots of different beeding materials over the years. If you are thinking of Bedmax for sheep bedding or for your goats, you would be able to use a lot less quantities than for a horse and would just need to pick up the droppings daily and then the wet sections at weekends. A bale or two would last you quite a while for this usage. It rots down very well too but when in use does not turn to dust as some shavings seem to do - stays in lovely large comfy flakes that smell of pine! It's also very light to manoeuvre around - even when very wet!
