I'm in a very similar situation. Hay isn't my problem. I have plenty of pasture and hay fields as we do our own hay. However feed prices are KILLING us. The Triple Crown Senior that a few of my horses eat has gone from 12 dollars a bag in September to 17 dollars a bag on Monday. My feed bill for 16 horses jumped from 350 a month to over 700. It was RIDICULOUS. I have given away 3 of my horses, 2 will be picked up on about 2 hours, 1 is already at her home and I still have a few others to go. We also sold our cows because they just flat out put pasture and hay away along with feed. We are replacing them with goats, I don't know how it will go but if it doesn't work we'll sell them too.
We are keeping chickens, ducks, goats, and we will ahve about 11-12 horses. Cats and the doggies. I still will have alot of mouths to feed but down a few horses will certainly help.
Fuel prices BITE, along with Feed prices too. I don't even want to talk about dog and cat food!
