Haha that's what you gotta do! These feed stores need to realise not every horse is the same and not every horse can live on the same diet. But I do get not wanting to have to buy in so much bulk they can't sell it.
I'm glad igot the right thing - thank you all so much for your help (especially desert who got me going in the right direction!) tonight she starts her new life!! The pony will finish off my regular grain as he's not nearly as bad as my mare - the he'll switch over too.
Mudpue lol yes why is that weird? It's about 35 minutes away but it's worth it xD
