If it wasn't crappy grass hay she would be eating it quicker. Why do you choose to feed crappy hay? I think it is important to feed twice a day so they have something in there belly's longer. Especially if it is cold the digesting keeps them warm.
You are probably right.
I feed her yuckier stuff (I've just really assumed that it was "crappy" because it's more of a golden brown, no green, but smells good and it's soft, she was eating only it last year and she was way too skinny, and she doesn't like it as well as most other hay, but it technically hasn't been proven to be legitimately crappy, that's just my opinion of it) because it's $4.75 for an 80 pound bale of local hay (the crappy stuff) compared to $12.95 for an 100 pound bale of Timothy (the other grass hay option). I figure that since I'm mixing it with alfalfa ($12.95 for 120lbs) and she's returning (she was a little too skinny, imo, in Nov.) to a perfect weight on that combo, why should I pay more for something that's working just fine currently? And since I'm just using it to keep food in her belly and not really for the nutrition content (she's getting enough alfalfa to be doing fine nutrition-wise, imo) It seems fine to me to go cheaper.
And, I have to feed her alfalfa because the llamas she lives with are fed alfalfa and otherwise, she'll just steal their food and not let them near hers, so they go very hungry.
I'd really like to understand where you're coming from though, why would it be bad to go the lower nutrition/protein route for belly filling hay?
Also, I haven't mentioned this on this thread, but Lacey is a laminitis/founder risk and she's a rather easy keeper, so I don't want her to be fat.
I like her to be a little round but I really think that she's naturally so muscular that what I think of as her being "round" is just her being super buff. She really is like an HYPP positive QH when she's muscle-y.
