I'm interested in all the different ways you all offer oyster shell & grit. Like what kind of containers (if any) & if it's just free-standing or attached. Is it close to the feeder or is it just somewhere out of the way that they can get to? My chickens free-range & seem to have enough grit around, so I've never fed grit, but when I hatched out some chicks, I did get some chick grit when they were a couple weeks or so old. So, I did start throwing a little out there in the chicken pen here & there just in case they need it. As far as oyster shell, I have one of those little plastic dishes that has the little lip thingy where it can hang on fencing & such. I keep it in there on the fence sort of out of the way. If the hens want it, they can get to it. I recently had a little bit left in the bottom of a bag & put it in an empty, washed canned cat food can & put it out there as well (opposite side from the other dish)...close to the feeder, but they turned it over & spilled it.
