I’ve been bedding straw for years now, and I love it and my horses love it. I am lucky to have a local farmer who sells me lovely, fluffy golden straw for under $3 a bale. One bale is enough to bed my 12X12 stalls rather luxuriously; I usually use less.
I have some of the greediest eaters around (including my dearly departed pony) and none of them have ever done more than nibbled on it. Perhaps oat straw might be tastier, I don’t know, but it’s never been a problem for me.
I have always cleaned with a standard shavings fork, and have gotten quite good at it. I can go under and pick up a “nest” of poops pretty handily now! I also find that since it is so much cheaper than shavings, I don’t have to be so meticulous about picking only the bad stuff out, so chores take less time.
The only big downside of straw is storage and disposal, because it is much bulkier than shavings (which I still use for a light, absorbent layer under the straw). However, I have a big loft and 80 acres to spread on, so it’s not an issue.
The only other thing I’ve heard people complain about is the smell, which is not good once they pee in it. However, my horses are out 24/7 for 3/4 of the year, and the other months I just keep things as clean as I can, so I don’t have an issue with it.
I also have a REALLY piggy mare boarding here now, and I can’t even imagine bedding her in shavings only, it would cost a fortune! This mare drinks two five-gallon buckets a night, and I swear she pees twice that! But with straw she always has a dry top layer to lay down on.
Also, I think that clean straw is better for their breathing, which is why it is commonly used for racehorses.
To each his own where horse keeping is concerned, but I love my straw bedding
