Tell me about rural! My granddaughter told a friend of hers one time, when her friend asked how isolated we are out here, "Well, let me put it this way - when Gramma says we're going to Walmart I say, 'Oh, goodie! I'll pack the cooler!'" Two stoplights in our entire county - that's not two stoplights in our town, that's two in the county! No house to house mail delivery. We all go to the post office to pick up mail. No bank, no grocery store (except the Merc, which is a gas station with a few grocery items) no full time cop, and our business district is on block long and on only one side of the street. But I love it! Have to drive 100 miles up to Billings for any big ticket items, the nearest feed store is 50 miles one way, the nearest McDonalds is a 25 mile drive one way. I love this place! One thing I forgot to mention. When my flock is mixed, meaning I have chicks, pullets, layers, and roosters, I don't offer layer feed. Instead I feed either grower or flock maintenance so the young birds and the roos aren't getting the added calcium that's in the food. Some say it has a detrimental affect on them and I don't know that for sure but I just err on the side of caution. I know a very respected long time chicken keeper who says it's hooey, and she's never been wrong that I've ever seen. Everyone in her flock gets the same food fermented and a ton of free range time. But just in case.... So the oyster shell container is always full. When it's first filled, they all dive in like it's a long awaited treat, but after a nibble or two the roos and chicks ignore it, while the layers still eat it when they need it. And I don't worry about the chicks and roos eating the eggs with the shells. As I said, I just don't think there's that much calcium left in the egg shells, so I don't sweat it and I've never had an issue. You will very rarely see the hens hitting the oyster shell. They mostly just grab a little once in awhile and wander off. Seems like once I fill the container it lasts forever!
