Yes, I can store it awhile, I have it under an awning. I was going to buy 200 bales.
At the feed store it's $7.50 a bale for "ok" hay. The man I bought my last load from charged $4.00 plus delivery and the hay was the equivalent or better than the feed store and the bales weighed about the same.
Hair, $10 a bale is really expensive. The hay that's available here is coastal bermuda and it's good hay, if you get it from a good supplier. I have bought hay that my goats had trouble eating. If a goat won't eat it, you know it's bad. How much is alfalfa up there?
Alfalfa is a ~little~ less, it's not so much in favor. I think it's around $8 for horse quality, lots of cheap alfalfa for cows.
$10 is for a big heavy bale.. I'd guess them to be 100-120 pounds. but you're right, it's expensive.
