Standlee hay quality can vary. I've had bales full of weeds, dirt, brown hay. Or you could end up with a good bale, if you want to take a chance. I don't know, ,maybe the small pet boxes they sell are selected for better quality than the full size compressed bales. I have good bales now, but I got them at the farm store where I could check them first before taking them home.
If you want hay that is more likely to be good quality, Small Pet Select has good quality hay. I've never bought it but I know of others on here that have and like the quality, and their rabbits like it. Second cut timothy is usually a mix of leaf and stem, and most often the cut sold and fed to rabbits.
