So my Eglu is on order and by the end of the month I will be the owner of 2 hens. I live in West LA so the feed stores which would carry everything is a bit of a drive, so I want to make sure I am all stocked up with everything I need in the first trip. So far on my list I have: Chicken feed (I start with the obvious ) Oyster shell Pine shavings black oil sunflower seeds And I'm supposed to get scratch grains? If I just say "scratch grains" to the store, I assume they'll know what I need? I also read that if your chicken will be directly on the ground/grass they don't need grit, is this correct? Is my list missing anything?
