If you're concerned about grain size, an el cheapo coffee grinder from amazon does a decent job for the first week or so while they're really tiny.
I had no choice but to use a 50 lb bag of medicated gamebird feed once. Didn't have any problems. 27 is pretty close to 30. I wouldn't sweat it. You can probably supplement with some mealworms after a couple of weeks to give them a protein boost.
